Monteverde MP1 Mercury Orange Fountain Pen Review

Monteverde MP1 Mercury Orange Fountain Pen Review

When Monteverde launched their MP1 Fountain Pen earlier this year, I was intrigued. I like the style, and it lands in a price bracket that could make it an option for users looking for their second fountain pen. You know, the one when you decide that “Yes, I like this stuff!” and you want more from your next choice.

The Monteverde MP1 Mercury Orange Fountain Pen is a Goldspot exclusive release, and a perfect fit for the season. They sent it over to me pre-launch, and I’ve had some time to spend with it recently. So far, it has been a fantastic writer, although there is a minor change I’d like to see updated if there is a version two.

Monteverde MP1 Mercury Orange Fountain Pen Ink

Packaged with a 15ml bottle of matching Mercury Orange ink. These sets are a limited edition of 300.

For starters, the MP1 is my aesthetic: Clear barrel, color anodized cap and piston knob, complimentary gold-plated hardware. This is a common barrel layout and design, and one I find myself using in other models frequently. The Mercury Orange aluminum that Goldspot chose for their pen pops off the desk, and in my hand.

The locking piston, pulled out. The two white dots line up for closure.

The piston mechanism has an interesting lock that keeps the knob in place when not actively using it. I’ve never used a pen with this feature before, and it is a simple pull to release and use the piston, and a snap back to lock it in place. Ok, maybe more than a simple pull and push - it is a two-handed operation to release - but it’s not going anywhere when locked. For those worried about carrying a piston-filling mechanism and having it twist in transit - like in a backpack, pen case, pocket, or purse - this gives you some extra peace of mind while on the go.

Monteverde MP1 Mercury Orange Fountain Pen Nib

When you arrive, the nib is ready to write, and never stop. This Fine Steel Jowo #6 nib has been perfect from the jump, with no adjustment needed. The feed is not the normal matching Jowo #6 feed, and it flows as good or better than what I would expect from a stock setup. The product description calls the feed “Plasma-treated,” but I have no idea what that means from a technical perspective. All I know is that it works well.

With all of that good, I won’t say that there is no bad, but more of a personal nit to pick with the usage of o-rings on this pen. O-rings can be used well, but I don’t believe either of the exterior barrel o-rings add anything to the pen. In fact, they take away. The end of barrel ring, just below the piston, is assumedly there for posting. The problem is that it forces the cap to stop right there, making for an extra long pen when posted. I don’t post, so I don’t use that area, but I’m not sure it is good if you do want to post it.

Longbois.

The MP1 is just shy of 7 inches posted.

The front end o-ring, just above the barrel threads is useful in concept, but doesn’t provide a great user experience. This o-ring is there to seal off the interior of the cap from exterior air entering and drying out the nib when not in use. That’s a good, valid issue with many pens. Monteverde chose this option, and it works well - I’ve had no drying out at all - but capping the pen feels off. It’s almost like the o-ring gets in the way, and the cap is wobbly as you begin to screw it on until you force your way past it. After that, you are sealed and good to go, but capping it was noticeably odd every single time I did it.

To be fair, the TWSBI ECO is designed with o-rings in the same places. Like with the MP1, the end of barrel o-ring isn’t useful unless you want to write with a baton. The front o-ring isn’t noticeable on the ECO until the final turn of the cap, which is exactly where you want it to be. In fact, I had to go grab one of my ECO’s to verify it was even there. The MP1 doesn’t engage in the same way.

Looks awesome, but it may be difficult to see that it is a molded, triangular-ish, grip section.

One not so nitpicky consideration if you like the looks of this pen is that it has a triangular/molded grip section, so if you have a non-standard grip you might want to pass. If the MP1 continues to do well, maybe they mix in a standard grip section, like TWSBI does with the ECO and ECO-T?

The Goldspot exclusive Monteverde MP1 Mercury Orange Fountain Pen runs $63 and includes a 15ml bottle of matching Mercury Orange ink, which is only available with this pen. A wide range of other colors of the MP1 range from $52 to $60, so they are all in the same ballpark. As I mentioned up top, this pen looks and feels great to write with, and the nib/feed combo keeps the ink flowing. The main consideration is if you can work with the molded grip section, or not. I can, so I’m going to keep on writing!

Kaweco Perkeo Calligraphy Set Review

(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!.)

The Kaweco Perkeo Calligraphy Set includes the Perkeo pen barrel and cap and three different grip sections, each housing 1.1, 1.5, or 1.9 millimeter nibs. 3 Kaweco Pearl Black cartridges are also included but I decided to use my Kaweco Midnight Blue cartridges instead. The set comes in a plastic box.

The pen, grip sections, and cartridges in a clear “tray”.

Since I have already done a review (of the Perkeo), I will focus on the Calligraphy Set. Not only does the set include 3 separate grip sections with the nib and feed, they are different shades of blue, so you can easily tell which nib you’re using. The light blue section holds the 1.1, the royal blue holds the 1.5, and the dark blue 1.9.

The light blue 1.1 section (left) is installed in the pen, 1.5 royal blue in the middle, and 1.9 dark blue on the right.

I knew that the Perkeo would work right out of the box (which it did), but I was really surprised at how nicely it wrote! It wasn’t scratchy but it also wasn’t uncontrollably smooth either. In addition to this Ayush paper, I also tried the smoother Meringue paper and this pen behaved like a champ.

I felt that I had spent a fair amount of time with the 1.1; after all, it’s been inked up since August 1, and used five times before this article, so it was time for the 1.5 nib. This one isn’t quite as smooth as the 1.1, but I think it is a bit more sensitive to angle than the 1.1. Most companies use 1.1 for their stubs so I find it fun to use a 1.5 for variety, and it’s a faster way to go through ink.

1.1 on the first paragraph, and 1.5 for the rest of the page.

Of course, after the 1.1 and 1.5, I have to try the 1.9 and it, too, wrote well out of the box. (The 1.1 and 1.5 nibs have been sitting out on my desk for a few hours so the ink is more saturated. The top of this page is a bit lighter because I put a drop of water on the breather hole to get the ink started.)

Love all the ink that gets laid down by a 1.9!

I liked all three nibs pretty equally, but the 1.9 forces me to slow down a bit more so my letters aren’t as messy.

Writing sample of the 1.1, 1.5, and 1.9 nibs.

The Kaweco Perkeo Calligraphy set retails for $40, which is a good deal for a pen with 3 nibs/grip sections.

(Disclaimer: I bought this set from Vanness Pens. I already had the Kaweco Midnight Blue cartridges and Ayush Paper.)

PS - A 10 ml vial is a great to store the grip sections (Clearly, I cannot grammar when writing! You know what I meant, lol!)

Kaweco AL Sport Piston Filler Fountain Pen Review

Kaweco AL Sport Piston Filler Fountain Pen Review

(Sarah Read is an author, editor, yarn artist, and pen/paper/ink addict. You can find more about her at her website and on Bluesky. And her latest book, The Atropine Tree, is now available!)

One of my favorite things to do is wander off to someplace scenic and then write a lot when I get there. Writing at home, where the dishes and laundry and cats and children are all competing for my attention, is nearly impossible for me these days. Really, I can write anywhere but at home, but good scenery helps. It's nice to have something pretty to look at as I stare into the distance for extended thinky time, which is 60% of the writing time.

Kaweco AL Sport Piston Filler Fountain Pen

But writing on the go has a conundrum. Pocket-sized pens are much more portable and easy to take on the go. BUT pocket-sized pens commonly do not hold much ink. I have a few trusty eyedropper pens that have served me well in these cases, but I was very excited when I learned that Kaweco was releasing a piston filler version of their pocket pen. I already love Kaweco pens, but a Kaweco with a built-in ink tank? Be still my heart.

I finally got my hands on one, and the verdict is: why do other pens even exist? That's a silly question, of course--I love all my other pens, also, and I wish I could write with every single one of them every single day. But this one really is the perfect "run away and write lots" pen. I believe we will have many adventures together.

Kaweco AL Sport Piston

Our first adventure was a few weeks ago at an all-day write-in at a winery in the middle of the countryside. The setting was gorgeous, the words were flowing, and this pen was a champ.

The Kaweco piston filler comes in two models, the Classic, which is made of plastic, and the AL, or aluminum model. I chose the aluminum one for its durability. It has the characteristic Kaweco Sport shape with the cylindrical body and hexagonal, long cap that covers most of the pen. The cap posts securely to make a normal length pen, though I prefer to write with it unposted. This model has a built-in clip, which delights me. It's the same design as their add-on clips, but this one won't slip off--though you can remove it by unscrewing the finial, if you want. The aluminum body is anodized a matte black and all the finishes are in gold tones, which gives it a very elegant look.

Kaweco AL Sport Piston Barrel

The grip section is slightly shaped for good grip, and behind the grip and threads is an acrylic ink window so you can see how much ink you have left.

At the bottom of the pen is a cap that unscrews to reveal the piston knob. I really like this design. While the cap is a small piece you need to keep track of, keeping the piston knob covered prevents any accidental twisting that could result in ink spillage.

Kaweco AL Sport Piston Nib

The pen has a gold plated steel nib. Mine is an EF, and it glides. It is so smooth, with just the perfect amount of flow. It's a fantastic writer. It never skipped or stopped for the entire five hours of writing I did at this retreat. It was the perfect pen for the day.

I received the starter set version of this pen, so it came in a beautiful presentation tin with a bottle of Kaweco's classic blue ink, which I was more than happy to fill it with. It's a lovely true blue and looks fantastic in the pen and on the page. The Starter Set AL Sport Piston Filler sells for $170 at JetPens, while the pen alone sells for $160.50. The Classic version in plastic costs $70. It's available in XF, F, M, B, and BB. And with this ink capacity, you could actually rock that BB. The prices all seem quite fair, in line with other Kaweco models. A regular AL Sport costs $76, so it makes sense that the added complexity and convenience of the piston model would be higher.

Kaweco AL Sport Piston Writing

This pen has been my daily pen since it was inked, and I still haven't had to refill it. This is going to be the perfect pen to take on longer trips without having to worry about running out of ink. There are a plethora of writing events coming up throughout the rest of the year, along with my usual November writing retreat and one long work trip. Kaweco will be my trusty sidekick.
