Pentel Brush Pen Medium Pigment Ink

Uses water-based pigment ink that dries quickly and has good color development.
There is little bleeding of the writing, and it is possible to write thick, clear letters even on highly absorbent paper such as washi paper.
Pigment ink has excellent water and light resistance.
When used as a drawing material for illustrations, etc., the colors will remain vivid even if you paint with watercolors or poster colors over the dried ink.
