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

very well Good product for a Pens and Ease of Cleaning and Functionality flows easy though the pen

I use a fountain pen daily. This ink appears to be much better than the other bargain brands I was using.

The best ink by far.Your scratchy and annoying pen will start gliding with this ink!

I bought this ink to go along with my Pilot Metropolitan with Con-40 conversion, and wow it is beautiful. From the presentation in its packaging to how it looks on paper, there’s no lack of style, grace, or quality here. Would buy again and recommend to anyone who appreciates writing.

All Iroshizuku inks are solid and write well. Some colors are so-so but you can't go wrong with a black.

Works well in my calligraphy pen. I don't know about other pens. Ink flows well from the nib without bleeding out of the track. Writing with it is ok, but for art work I prefer a slightly thicker ink. It seems that most inks today are similar to Pilot.

The color is black, as expected, but has a certain depth to it even when dry. Lubricates the pen as it's used, and is a fantastic ink for amateur calligraphers like myself. Truly, the WD-40 of the ink world!

Big fan of this ink and now have it in three colors. I had been using another brand of black ink in my Lamy fountain pen and had all kinds of issues with getting consistent ink flow or having the ink go dry after a day or two of not writing with it. I assumed it was something wrong with the nib or cartridge but when I switched to this ink my pen instantly started writing better.
