Copic Gasenfude Brush Pen
The Copic Gasenfude Brush Pen was created with sumi-e (East Asian brush painting) artists in mind. Its long, flexible brush tip creates expressive line variations for calligraphy or illustration. Filled with water-based pigment ink, this pen is water-resistant and Copic-proof (it will not bleed when used with Copic markers) when dry.
