Kuretake Keicho Fude Brush Pen - Black & Grey

A double ended fude pen with black at one end and grey at the other, which sounds simple and turns out to be the whole point. You can shade and blend without switching tools or breaking rhythm.

Both tips are softer than a standard brush pen, so the difference between a hairline and a full stroke is mostly a matter of how hard you lean.

Fude pens come out of Japanese calligraphy but travel well into drawing and lettering. Marker sized, so it lives in a pocket rather than a case.
