Ink Institute Taiwan’s Secret Realm Lavender Coral Ink 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!)

I might have said, recently, that I don't need any more ink--that all the colors on earth are well represented in my collection, and that I could write forever with the supply that I have. But when I said that, I hadn't met this ink yet, so. Past Sarah was wrong.

Ink Institute Taiwan’s Secret Realm Lavender Coral Bottle

The Ink Institute Taiwan’s Secret Realm ink in the color Lavender Coral is in that favorite color family: a dusty purple with pink and blue undertones and heavy shading that shows all the complexity of the color. There are lots of inks in this flavor family, but they're notorious for being quite pale and sometimes even unreadable in low light. Still lovely, but more pretty than practical. Lavender Coral, though, is saturated enough that it hits those soft color tones while still being bold enough to be practical. And I am enjoying it so much.

Ink Institute Taiwan’s Secret Realm Lavender Coral

This is my first Ink Institute ink, so I can't compare it to their other offerings. (Yet. I now have my eye on a few. Help.) I've enjoyed the experience getting to know this ink. It comes in a fancy box with a slipcase and some lovely art. The 30ml bottle is frosted glass. It looks great and is practical for keeping direct light away from the ink inside. It has a metal screw cap. The bottle opening is a bit narrow, but not unreasonably so. The bottle felt stable while I was filling the pen.

I was happy as soon as I started writing. The ink has great flow. It is described online as a dry flow with fast drying, but I did not find that to be the case on my Kokuyo paper. It hadn't dried after 30 seconds, when I stopped timing it. But I like wet inks, so that's not a negative in my book. The slow dry time helps with the incredible shading, I think. The ink starts out looking like a smoky blue-grey, and the lavender-pink tones develop as the ink dries. In the shaded areas where the ink pools, the deeper purple shows, and a great complexity of color shows around the edges. Have you ever just sat and watched in transfixed delight as ink dries? Don't lie, I know you have. This was a 10/10 watching ink dry experience.

Ink Institute Taiwan’s Secret Realm Lavender Coral Chromatography

The chromatography shows just how many colors are hiding in this ink, and how the bright colors have blended into something softer. There's also no feathering or bleeding, even with heavy use.

Ink Institute Taiwan’s Secret Realm Lavender Coral Writing

This ink isn't waterproof or water resistant, though some hint of purple stayed after a water spill test. The dramatic shading shows well in writing, and it builds with multiple layers, which makes it great for artwork. I'm very excited to continue writing with it. It's a contender for a new top favorite for me, as it has a similar effect as a previous favorite that isn't as easy to read.

Ink Institute Taiwan’s Secret Realm Lavender Coral Water

The 30ml bottle sells for $21, which is a little pricey. A 50ml bottle of Sailor ink is $18 to $24, for comparison. A 30ml bottle of Diamine is only $8. So this ink is toward the upper end of the spectrum, price-wise. Would I buy it at that price? Yes, even though I said I'm not buying any more ink. Maybe that's saying something, but maybe it isn't. What I can say is that it's a pleasure to write with it, even if I spend as much time staring at the ink and watching it dry as I spend writing.

Kobe Ginza Gold Sepia Fountain Pen Ink Review

Kobe Ginza Gold Sepia Fountain Pen Ink Review

I seem to have two modes of ink buying: Weird, or Blue. Shopping for those non-traditional shades is one of my favorite things to do, and my counterbalance is popping a basic Blue ink cartridge into a pen and going to town.

While I keep a good stock of basic inks at hand, the weird inks are the ones that get me going. Kobe Ginza Gold Sepia fits the bill perfectly.

Kobe Ginza Gold Sepia

One of my favorite questions to ask when shopping for weird inks is “what color is it?” You would think that would be a straightforward question to answer, but with modern inks it can be more difficult than you think. So, what color do I think Ginza Gold Sepia is? Sepia, with a hint of Gold. Sorry to disappoint you, but the name is accurate!

I keep trying to see other colors in this ink that would allow me to describe it differently, but I don’t see them. Sepia Brown is the primary shade, with Gold being more of an undertone in the lighter areas of the lines and swatches. And in all honesty, I would like to see more funkiness to it, more shading, maybe a hint of Green?

Kobe Ginza Gold Sepia Swatches

I tried this ink on a variety of papers to see if I could get something to pop. Between Graphilo, Crena, PLOTTER, and two types of Midori, Ginza Gold Sepia remained Ginza Gold Sepia. I’m acting like this is a negative, but it’s not. Not even remotely. In fact, the consistency is to be commended.

Kobe Ginza Gold Sepia Writing

This is also why I chose an Extra Fine nib for this review. Seeing ink characteristics in a swatch is one thing, but seeing an ink in its natural writing form (my writing form, to be specific,) is valuable. I want to know if this is an all day, every day writing ink more than if it will be good for Ink Pony Club.

Ginza Gold Sepia is an all day writer, but I’m left wondering how often I will choose it over more pure Brown or Sepia shades, or over something ultra funky like Rohrer and Klingner Alt-Goldgrün? I don’t think that often, but we will see how it goes.

Kobe Ginza Gold Sepia Nib

I bought my bottle directly from Nagasawa at the 2025 California Pen Show, and you can pick yours up for $30 from Vanness Pens, or try a 4 ml sample. Kobe Nagasawa inks are made by Sailor, and meet the high performance expectations I have from the brand. It’s perfect from any nib, and on any page. Now to see how frequently Ginza Gold Sepia will be the perfect shade for me to use.

Endless Stationery Alchemy Inks Series — Poseidon's Reef Review

Endless Stationery Alchemy Inks Series — Poseidon's Reef Review

(Jeff Abbott is a regular contributor at The Pen Addict. You can find more from Jeff online at Draft Evolution and Twitter.)

The Alchemy Inks Series from Endless Stationery is a fun collection of inks that all tell a story of how an alchemist was able to wield the power of each ink with the help of gods of legends. With Poseidon's Reef, we get a lovely teal ink with heaps of red/purple sheen and a bit of shading to mimic the look of shallow ocean water.

Endless Stationery Alchemy Inks Poseidon's Reef

I'm personally powerless to resist adding a new blue, teal, or turquoise ink to my collection. At least with Poseidon's Reef, I get a nice dark teal ink that has a massive sheen flair that shows up on the page easily. The shade is a dark blue with a hint of green that turns it into a teal color. It's a pleasant color that somewhat reminds me of the ocean, but the slight bit of shading and hue variation adds more to that allusion. I'd like it if the ink had more shading variation, but the subtle effect is nice.

Endless Stationery Alchemy Inks Poseidon's Reef Sheen

The characteristic that really surprised me with this ink is the sheen. There's an obvious and abundant red and purple sheen on this ink once it dries. Even in smaller nibs, the contrasting sheen shines through the dark teal background. It's a great effect, and one that really distinguishes this ink from other similar dark teal inks.

Something else that surprised me is the amount of time it takes this ink to dry. It's mostly dry by 15-20 seconds, where only some small areas still smudge with moderate pressure. In normal writing circumstances with a fine nib, I was able to write and immediate wipe my hand over the page without causing any smudges. The ink will still smear for left-handed writers, so we can't add it to the esteemed list of super-fast drying inks. Still, it dries fast enough to be worth mentioning.

Once you get past the color and sheen effects, there's one characteristic that I've noticed that I don't like. In certain circumstances, the ink tends to feather and bleed. It doesn't happen all the time, which makes me think it has something to do with the paper. Still, it happens about once per sentence and is noticeable.

Feathering aside, this is still a wonderful ink. The flow is smooth and steady, the color is deep and mysterious, and the intense sheen is a lot of fun. The bottle that Endless Stationery use for the Alchemy series is a fun design as well. The base of the bottle is convex, which causes the bottle to twirl around gently. I definitely wouldn't let it twirl with the lid off, but you also get a nice cork stand that keeps the bottle steady when you're filling your pens. It's a fun bottle design, but definitely not something that should influence anyone's decision to buy. The artwork on the box is also fun, with a detailed illustration of Poseidon next to a coral reef with a holographic effect on the box that shifts the colors.

Endless Stationery Alchemy Inks Poseidon's Reef Bottle

Poseidon's Reef is $20 for a 45 ml bottle, but you can also pick up a small 4 ml sample vial to try out if you're not sure you want the whole bottle. There are a few other color options in this series, and I look forward to trying some others!
