Iroshizuku Bottled Fountain Pen Ink, Take-Sumi, Bamboo Charcoal (Black) 50ml Bottle (69224)

The Pilot Iroshizuku line is everything a fountain pen enthusiast could ask for. The ink flows like silk — smooth, consistent, and perfectly balanced between wet and dry. It performs beautifully on both premium and standard paper, with no feathering or bleed-through when used with a good pen. What really sets it apart, though, is the color quality. Each shade has incredible depth and nuance — whether it’s Kon-peki’s vibrant blue or Yama-budo’s rich wine tone, they all have a subtle shading that makes your writing come alive. The bottle design is stunning, too — thick glass, elegant shape, and easy to fill from. Yes, it’s a little pricey compared to standard inks, but the craftsmanship and performance justify it completely. Pilot Iroshizuku proves that ink can be more than just functional — it can be a work of art in itself.

I have used this ink in a Hongdian Black forest pen for several weeks and love how it looks and flows. It leaves a crisp, clean line that dries quickly. I have read that it is a thin ink and bleeds through the paper. I have not had this problem. I normally write on Navigator 32lb premium paper but have tested this on pages of a $1.29 pen + Gear steno book and have had no bleed though on either. I initially balked at the cost of this bottle of ink until I compared it to the cost of using pre-filled cartridges but quickly changed my mind when I looked at the per milliliter cost. When compared to the amount of ink in Parker Quink cartridges, for example, this ink is about a third of the price. It is worth every penny

This is my favorite ink right now. Flow and color is beautiful

As an avid fountain pen user, I have purchased and tried oh so many different inks in just as many pens and nibs... I recently bought an extra fine nib from Kaweco and I could not for the life of me get it to stop being scratchy and uneven, even with Kaweco ink....UNTIL, I used THIS ink. Now it writes BEAUTIFULLY. There's just something special about this ink that it always writes smoothly in every pen. I will 100% be buying this ink from now on and in additional colors. I find it to write very smoothly, no feathering, on all kinds of paper, with all nibs of various brand and size, and it never skips or gives me trouble. It's just gorgeous and unflawed. I also really enjoy the packaging. I think the simple yet elegant bottle looks professional but adds to the environment as it's attractive in and of itself. I truly cannot love this ink more. I prefer this ink over many, many popular brands I have used. This is beginner friendly, it's well worth the price. This bottle will last quite a while. It's very much worth it. I would highly recommend this ink to all fountain pen users for whatever the purpose. It's fantastic!!

Take-sumi Iroshizuku Fountain Pen Ink by Pilot is a true gem that deserves a 5-star review! Ink has quickly become my go-to choice aside from GvFC Carbon Black for writing and it’s also dark, flows smoothly, and just brings out joy when writing The dark black hue is very good - not as dark as Noodler’s and Aurora, but it’s a good darkness of black without the hassle when cleaning your pen since it is water-based. It dries fairly quickly and has a little bit of highlighter resistance to it as compared to GvFC. Glides effortlessly across the paper even when using Walmart brand Pen+Gear Stenopad. This is a good choice ink and would recommend if you are looking for high-quality ink

I use this ink with a Cross Century fountain pen. The ink glides on the paper rollerball fashion. Almost like laquer. Dries very quickly. I love it.

I bought this for drawing with a G-pen mistakenly - didn't know Pilot had a specific ink for drawing and this ain't it, haha. It's not bad. The bottle is very fancy, and the ink is nice and black. It also works with alcohol markers, provided you let it dry properly and don't go over it too much with the marker. HOWEVER. It feathers like crazy if you get any hand oils on the paper. I ruined several drawings before I figured this out!! So whether you're writing or drawing, consider wearing an artist's glove to protect your work.

Great ink

La tinta se ve hermosa, tiene una densidad adecuada para la escritura y se ve que está diseñada para una escritura en papel con un gramaje pequeño sin problema pero en uno grueso puede desmeplarse mejor

Just opened the bottle and happy to see that bottle is intact and cap not broken. Yet to use the ink and see the colour if I will like it as it is my first time using this colour.😃

The ink writes beautifully s mooth flow, rich colour and clean drying. It feels refined, behaves well on most papers and makes everyday writing surprisingly enjoyable. A lovely choice for any fountain pen user.

I have used black from various other companies, like Mont Blanc, Parker etc but this is my favourite. Lovely, black and as with all Iroshizuku inks, it flows very well...

Muy buena tinta, un tono negro suficientemente saturado.
