A Trio of 2025 Chicago Pen Show Inks

(Kimberly (she/her) took the express train down the fountain pen/stationery rabbit hole and doesn't want to be rescued. She can be found on Instagram @allthehobbies because there really are many, many hobbies!.)

One of my favorite things to get at a concert, show, event, or shop, is something that reminds me of the occasion, whether it’s a t-shirt, bag, or sticker that makes me remember that event. In the case of pen shows, it’s no surprise that I am a sucker for show-exclusive inks!

At the 2025 Chicago Pen Show, I bought several bottles of ink, but 3 of them were specifically made for this show! The first one is the official show ink, Windy City Blue, made by Colorverse to celebrate the show’s 45th anniversary. The second one is Papier Plume Lake Michigan Springtime. And last, but not least, is Anderillium’s Chicago River Green.

Note: I add swatches to similar color family inks in both the Hobonichi Weeks and 68 gsm Tomoe River notebook. Unlike the Col-O-Ring swatch card comparisons, the Weeks and TR swatches might not be that close to the ink in question.

Despite the box and bottle’s lighter blue color, the Windy City Blue is more of a darker blue-leaning teal.

You can see a hint of red/purple sheen in wetter parts of the swatch and writing sample.

Inks similar to Windy City Blue: Rohrer & Klingner Verdigris, Robert Oster Lake of Fire is the closest match, Van Dieman’s Hanging Lake, New Brew Space, and Robert Oster Great Southern Ocean are also close but a touch too blue.

I’m eager to put Windy City Blue in either the Sailor x Cult Pens Pro Gear Slim, Midnight Sky Blue or the Leonardo x Figboot on Pens Momento Zero, Carolina Midnight.

I love that Papier Plume dips their ink bottle caps in wax and then stamps the top.

My swatches of Papier Plume Lake Michigan Springtime look fairly green but I’ve seen some swatches where it has more teal to it. I double checked with some friends who agreed that theirs is also more green in real person but looks a bit more teal in photos.

Inks similar to Lake Michigan Springtime: Waterman Harmonious Green, Jacques Herbin Vert Metropolitain, Wearingeul Tick Tock Croc, Diamine Velvet Emerald, Iroshizuku Sui-gyoku (this and the Diamine are a touch too blue), Diplomat Deep Green (a bit too dark.)

The Kaweco x GoldSpot Pens Sport, Transparent Turquoise (which is way more of a teal than turquoise), and the greenish parts of the Aurora Optima, Azzurra are both good matches for Lake Michigan Springtime.

Anderillium Chicago River Green is a pleasantly bright, spring green ink.

Inks similar to Chicago River Green: Diamine Appletini (too yellow), Papier Plume 2019 SF Pen Show Marina Green, Robert Oster Envy (both of which are close but still too yellow), Organics Studio Frog Green Shimmer, Diamine Merry & Bright (the closest), Van Dieman’s Wasabi (second closest.)

Anderillium Chicago River Green would look great in the Taccia Spotlight Forest Eye or the Kaweco x Cult Pens Apple Green.

Even though I can find similarly colored matches for all 3 inks, I still love having them as souvenirs of this year’s Chicago Pen Show. The inks cost $15-20 per bottle and are a great way to remember a fun pen show. If you didn’t get a chance to snag them, you can reach out to Roger Wooten, (show organizer) to see if they are willing to sell/ship the Colorverse ink. You can order Anderillium Chicago River Green from Atlas Stationers. Papier Plume is currently sold out of Lake Michigan Springtime but you can add it to your wishlist in case they decide to make more.

(Disclaimer: All 3 inks were purchased by me at the show at regular price.)

Colorverse Maryland Blue Crab Ink Review

Let’s be clear about something: I’m easily enabled. There are tiers of enabling, though. For example, “Hey Brad, LAMY has a new release, have you seen it?” Whether I answer that question with a yes or a no, I’m already on my way to buy whatever it is to get a look at it.

A much lower tier would be something like Blue ink. I have a Blue ink infestation on my ink shelf as it stands right now, with many shades represented. So when someone says, “Hey Brad, you should check out Colorverse Maryland Blue Crab, it’s an interesting Blue ink,” I have no business even considering adding yet another Blue to the collection.

But we wouldn’t be here now if I didn’t buy it, would we?

Once I looked at the swatch of Blue Crab, I did think it looked interesting, so I added it to my cart. Once it arrived and I inked it up, it looked better than I expected on the page. The best part about it is that I can’t exactly explain why.

Blue Crab was created by Colorverse to represent Maryland, as part of their USA 50 States series. These large sets are always fun to play around with, seeing what they come up with to represent - in this case - States. And Blue Crab for Maryland? How perfect is that. What did you think they would choose, Natty Boh?

The description of this ink is listed as “pale sky blue ink with medium shading,” and while I agree with the shading description (which I love, btw,) I’m not sure I would call the color pale. Dusty maybe? Is there a difference between pale and dusty even? I’m not sure, but my point with Blue Crab, and the challenge I’m having, is how to describe it.

There are many ink descriptors we like to use - bright, saturated, light, dark, moody, etc. - and I’ve yet to be able to nail down this one. It’s weird and normal, odd and fun. It makes me like it more that I can’t define it specifically.

I used a prototype Esterbrook (sorry!) with a Journaler nib grind with Blue Crab, and I love the pairing. My letters look so good, mainly because of the shading the ink has. The grind, similar to a Stub nib, helps pull and pool the ink within my letters, from top to bottom, giving them that cool two-tone look we call shading. It’s my favorite aspect of this ink, and has me wanting to write more and more with it.

There are no performance or color downsides to Colorverse Blue Crab, but the bottle leaves a lot to be desired. I don’t mind 15 ml ink bottles, but the opening is so small that you are only getting a converter or syringe inside of it to fill your pen. I can deal with that, but if you aren’t prepared, that could be annoying. Also, at $13.50, it’s not exactly cheap per milliliter. There are many better values on the market.

In the case of Colorverse Maryland Blue Crab, I wasn’t going for value. I was going for CRABS! And I got them, in the form of a color I look forward to using frequently. Nicely done.

Colorverse vs Kakimori - Dip Nib Showdown

(Kimberly (she/her) took the express train down the fountain pen/stationery rabbit hole and doesn't want to be rescued. She can be found on Instagram @allthehobbies because there really are many, many hobbies!.)

I first reviewed the Kakimori dip nibs (along with several others) in my dip nib comparison article a while back, so I was very excited when I heard that Colorverse was coming out with their own version of the dip nib, called the Shuttle nib.

I am using the same methodology for the Colorverse Shuttle nibs as I did last time with the others:

1. Ink - I am using Waterman Serenity Blue as a baseline for the swatches/writing samples. This is most nib grinders’ preferred ink of choice as it has consistent flow, does not stain and is good for vintage pens. I also picked a shimmer ink to see if it behaved differently. I capped and shook the vial between each test.
2. Paper - I used a combination of a 68 gsm Tomoe River notebook, a 80 gsm Rhodia graph pad, and the standard sized Col-O-Ring cards made from 160gsm paper.
3. Cleaning - I have used the steel Kakimori dip nib as my primary swatching tool for the past couple of years, so it has been rinsed/cleaned/wiped many times. I use tap water to rinse between uses.
4. I use a syringe to gently shoot water downwards towards the tip of the nib.
5. I do not dip the nib/holder into water and swish for cleaning, so I don’t get ink stuck inside the holder.
6. Writing - Aside from the name of the dip nib, I tried to write the same text on the different papers so you can see how much writing I could get out of one dip. For the Colorverse nibs, I will write a line without an initial cleaning, so I can see whether it writes on first use. Then I will rinse/dry it before rewriting the line again.
7. Swatches - I am making a broad line swatch as well as my typical Col-O-Ring swatches with both sets of nibs.

Note: After about 6 months of use, the Kakimori dip pen holder started allowing the dip nib to slide out of the ferrule (the “round thingy” that holds dip nibs in place). I showed a video to Kakimori, who ended up replacing the holder. Unfortunately, the replacement started doing the same thing some months later, so I stopped using that holder. I have also since misplaced it, so I don’t have any comparison photos of it next to the Colorverse holder.

The Colorverse Shuttle nib is packaged in a black box with holographic logo/design (right), which is then encased in a simple black box sleeve (left). The nib holder is similarly packaged but in a longer box (not pictured).

The Kakimori’s packaging (left) has a very different aesthetic. For lack of better words, I would say it feels more organic, while the Colorverse packaging gives off a very modern, space-like vibe, appropriate for its Shuttle namesake.

The hand marked check matches the rest of the Kakimori’s packaging aesthetic. Easy to see at a glance Colorverse’s brass or steel nib.

Before I get into the nitty gritty, let’s just get this out there ‘cause I know you’re dying to know if they are compatible with other holders. And the answer is YES! Both the Colorverse Shuttle and Kakimori dip nibs fit in standard ferrule nib holders, and yes, both will fit into the other’s nib holders as well! This is great news for folks who already have nib holders for the Kakimori or other dip nibs (neither will work in oblique nib holders).

Colorverse Shuttle aluminum nib in a Tachikawa holder, Kakimori steel dip nib in the Colorverse Shuttle holder, and Shuttle brass nib in a Speedball holder.

You can easily fit a Zebra G or pretty much any other standard dip nib in the Colorverse Shuttle holder.

There’s no denying that the shape of the Shuttle nib is similar to that of the Kakimori, but they are also a bit different. The Shuttle is a longer nib and has sharper channel grooves than the Kakimori. It is also more narrow and pointed, while the Kakimori is a bit broader and more “rounded”. Both of these differences factor into how the nib feels when using them at more extreme lower angles.

Colorverse Shuttle nib on the left, and the Kakimori nib on the right. Both are Brass and are in the Tachikawa holder, which has a standard dip nib ferrule.

Despite using a very light touch at more horizontal angles, the swatches still show “scratch marks” where the nib scratches the Col-O-Ring. I didn’t feel this quite as much on the much smoother TR 68 gsm paper, but neither performed quite as smoothly as the Kakimori.

The Colorverse Shuttle nib holder has a ridged grip section, which is neither too smooth nor too sharp. It makes it easy to hold without your fingers slipping. It is slim with a bit of heft to it, unlike a traditional wood or plastic dip pen holder which is very light. As such, it can be a bit uncomfortable for long term writing if you prefer a lighter pen or more girthy grip section or both. This nib holder is the Large model and is 7.4”/187 mm. There is also a Small one which is ~5.6”/142 mm.

Thanks to technology and poor photo editing skills, here is an approximation of the Kakimori holder (left silver) with the Colorverse Shuttle holder (right center). The holders on the left/right sides are from Tachikawa and Speedball.

The Shuttle nib holder doesn’t look like anything more than a ferrule in a ridged-grip long nib holder. The grip actually unscrews itself from the rest of the “barrel”, revealing a brass ferrule which is still attached. When attached, this piece and the grip form a gap which holds the dip nib in place. This brass piece is also detachable from the holder, making cleaning easy if you somehow manage to get ink back there. Unscrewing the section also makes it easier to fit into shorter cases/pouches.

Grip section unscrewed from the nib holder. You can see that the piece that holds the ferrule is still attached to the rest of the holder. It would be cool if you can get grips with different materials, designs, etc.

You can unscrew the ferrule if you need to disassemble it further to put it in a small case or for further cleaning. I wonder if the ferrule is replaceable - that would have solved the problems with my Kakimori holder.

For the writing sample below, the first part was done with the Shuttle nib right out of the box without any rinsing or cleaning. I did a quick wipe with a napkin to ensure no particles would get in the ink.

Making my swatch line with the Aluminum Shuttle nib. There is less of a curvature of the Shuttle nib, so I had to use a very low angle in order to not cut the paper or make much thinner lines.

Writing samples on Rhodia 80gsm (left) as well as writing at some different angles

This was really hard to do towards the bottom of the page of a super thick notebook, especially for someone like me who is also used to writing at 75 degrees.

One of the things that differentiates the Colorverse Shuttle nib from the Kakimori nib is a small reservoir which stores a wee bit of ink so you don’t have to dip it as often. I dipped it a few times because I could see that it was a surface tension bubble as opposed to ink in the reservoir.

Ink in the nib reservoir.

After dipping and confirming ink was in the reservoir, I managed to write a bit more than 1 page of A5 slim, which is about 3-4x what I got from a non-reservoir dip.

The number of pages you get will depend on multiple things including writing angle (my steep angle meant that ink flowed down faster initially), and how the reservoir is oriented (I had it facing up, but in another writing sample, I rotated it almost face down and got a lot more/too much ink flow).

Like I did with the Aluminum nib above, there was no cleaning of the brass nib prior to first writing. Not gonna lie, I absolutely HATED my Kakimori brass nib, so I was pretty nervous about how the brass Shuttle nib would perform. No need for worry as it wrote right away with zero problems whatsoever!

Swatch line and Rhodia samples. I had a bit more trouble writing on the Col-O-Ring than I did with the Aluminum nib, which surprised me.

Different angles on TR 68gsm and Rhodia. I rotated the nib a bit while writing at the 20 degree angle on top, hence the drastic line width compared to the Rhodia sample.

After dipping and confirming ink was in the reservoir, I managed to write a few lines more with the Brass nib than I did with the Aluminum nib.

In general, the two Colorverse nibs wrote similarly for me from 45-75 degrees (these were all done as “below reservoir” dips, aka, not super saturated, but with plenty of ink to write with). The widths were a bit more noticeable around 30 degrees and even more so when lower than that.

The angles are approximate and how much ink is left on the nib will also affect its width. Colorverse Brass (top), Aluminum, Kakimori Brass, Aluminum.

Both the aluminum and brass Shuttle nibs handled shimmer without any issues.

Alongside other dip nibs using the same Robert Oster Glistening Orange Rumble ink sample.

TLDR: If you don’t already have a Kakimori dip nib, the Colorverse Shuttle dip nib would be a good purchase, especially if you want to use it more for writing. I had a slight preference of the Brass because the line was just a wee bit thicker and held a bit more ink, though I probably would never use it for more a lot of writing (that’s what FPs are for, lol), But, I liked the Aluminum for writing on Col-O-Rings more than the brass. On smoother paper like Tomoe River, I liked either of Shuttle nibs a bit more than the Kakimori steel nib (and we all know how I feel about the Kakimori brass regardless of paper). However, given that my primary swatches are done on Col-O-Ring cards, the steel Kakimori feels smoother when making the large swathes of ink. You may like or dislike how either nib feels on different kinds of paper (like textured papers or watercolor paper versus Tomoe or Rhodia) or if you plan on using it for writing versus art, etc.

I would hands down get the Colorverse Shuttle nib holder over the Kakimori because I don’t have to worry about the nib eventually sliding out of the ferrule like what happened with 2 of their nib holders. Plus I like the ability to disassemble it in case of inky accidents.

The Colorverse Shuttle nibs cost $42 and $48 for the Aluminum and Brass, respectively. The nib holder in Aluminum costs $75 and $60 for the large and small, respectively, while the Brass holder is $85 and $67. They are priced similarly to their Kakimori equivalents. You can find the Colorverse Shuttle products on the Pen Realm website.

(Disclaimer: The two Colorverse Shuttle dip nibs and the nib holder were purchased from Pen Realm at the 2025 CA Pen Show. All of the other products are my own, including the Kakimori nibs and various holders.)
