"Water-based pigment ink" using fine pigment ink
We have created an ink that reduces the handling difficulties that are unique to pigment inks, so that it can be used comfortably with a fountain pen.
Water and light resistance
The characters written on it do not smudge even when wet, and the color lasts longer than dye ink, even when exposed to sunlight or indoor light.
Does not bleed through
It has the feature that the written characters do not easily bleed through to the back of the paper.
