Pilot Iroshizuku Tsukiyo Ink Review

Pilot Iroshizuku inks are one of the favourites among fountain pen users and for good reason. If these are within your budget, they are great inks that behave well and have some interesting colours. Tsukiyo is no exception.

Packaging

As you can see, the bottles for Pilot Iroshizuku inks aren’t your average run of the mill plastic or glass bottle. It is not only gorgeous but also practical with a small dip at the bottom which allows you to fill even when the ink level is low. The thick glass also makes the ink bottle pretty heavy.

Of course, the packaging adds to the cost of the ink, but the bottles feel so expensive and luxurious that I feel like that price has been justified a bit.

Colour

Tsukiyo is a blue that verges on being a blue black, but doesn’t quite get there. It has a hint of green, but it isn’t quite a teal. There is also this dusty, muted tone to the colour that distinguishes it from other inks in my collection. Overall, despite me owning a lot of blue and blue black inks, there is something unique about this colour which I quite enjoy.

There is also some red sheening where the ink pools, but quite a lot has to be laid down for this to be seen. Tsukiyo also has some good shading, with the colour ranging from a lighter blue to a dark navy colour. This is most evident in stub nibs. You can see in the image below, that even in fine and drier nibs, the ink is still quite dark and readable.

Ink Behaviour

Even if the bottle and the colour is pretty, the price can be hard to justify if the ink performs badly. Fortunately, Tsukiyo is like other Iroshizuku inks in that it behaves really well and I’ve never encountered any issues with it. Dry times are on the shorter side and there is no bleed-through or feathering, even on cheaper papers. There can be some slight ghosting when used in a wet or broad pen, but that is something you will see on most dark inks. Tsukiyo is not a waterproof ink, like others from the Iroshizuku line. However, despite the colour fading pretty drastically, there is still enough left to be able to read your writing. Writing with this ink is a smooth and pleasant experience with it flowing well, even in drier pens. Tsukiyo is neither dry nor particularly wet.

Ink Colour Comparisons

I thought I would have something similar in my collection but it turns out Tsukiyo is pretty unique. As you can see from the image above, the hint of green and dusty hue really comes out when compared to similar dark blue inks. Shinkai has a similar feel but does not have the green and is more of a blue black. I also put it next to Diamine Teal, but that ink is a lot more green and by comparison Tsukiyo looked like a straight blue.

Conclusion

Overall, Tsukiyo is an ink that I enjoy using in my pens (like other Iroshizuku inks). I have used in a handful of different pens and have had no complaints at all. There is just this luxe feeling that I get whenever I use Iroshizuku inks, maybe its just the packaging and the price tag, but I am definitely going to continue using these inks. I would highly recommend trying this ink out if the colour interests you.

TL;DR: Great ink if the colour interests you and it is within your budget.
