Sailor Kiwa-Guro Pigmented Black fountain pen ink is a high quality choice for the deep rich color and its fast-drying and water resistant properties. This pigmented ink was designed for brush pens, but is safe for use in fountain pens as well. A little extra care is called for, so don't leave it in your pen for weeks on end without cleaning. The pigment particles, if left to dry, can require a little more maintenance to clean out. Sailor Kiwa-Guro Pigmented Black fountain pen ink dries on the surface of the paper and is perfect for mixed-media or watercolor artists who use thicker sketch or watercolor paper, but this also works well for artists or others who use fountain pens, with a color wash over top.

When I first used pigment based inks in fountain pens, I checked often for any effect on ink flow due to clogging. I have had no such problems with Sailor Nano inks. Kiwa-guro is indeed ultra black like traditional calligraphy inks, and risk free in fountain pens! For example, I use it in a Pilot Custom 912 with an FA (falcon flex) gold nib and the effect is wonderful.
I love this ink, it isn't _jet_ black but it's black enough and shades into a texture-y dark gray. Dries relatively fast. Shipping was superfast, and the ink was well packed.
