Popular in Japan for many years, this high-quality brush pen or "gasenfude" is ideal for hand lettering, calligraphy, comic art or traditional brush art applications. Create lush black linework with ease and control; once dry, apply wet media with no bleeding or smudging. The thickness of the mark depends on the angle of the pen, the quickness of the stroke, and the texture of the paper - whether you aim for a bold stroke or a superfine line, this brush pen will produce beautiful results.
