On smooth paper it takes quite a while to dry, and it's not as opaque as it should be.

Fine addition to a brush pen collection with a quick-drying and fairly water-resistant black pigment ink. The Kuretake Zig Cartoonist Brush Pen No. 22 features nylon filaments and water-based black pigment ink. It can yield a fair variety of strokes of varying width by adjusting your drawing pressure. It looks very similar to Pentel Color brushes. Its synthetic brush tip felt quite smooth on regular card stock, and it was quite fun to doodle with. The black outlines dried waterproof quickly, for I was able to color them with the Gansai watercolors without any noticeable smearing of the inked sketch right after.

needs to be allowed to dry for a while (1/2-1 hr) but is then water proof, can be used with copics, but as somebody else said lifts somewhat when erased which is unfortunate. its pretty angelic to use though, really smooth and easy to variate line width havent been able to stop using since i bought one.

Best brush pen I've ever invested in. Nice bristles, good ink flow. Definitely worth the money.

LOVE this pen... now to find it... word to the wise... don't do lettering in bed!!! lol
