I couldn’t resist making my own pigment ink waterbrushes, because I had waterbrushes to spare.
From left to right: a Sakura waterbrush filled with highly diluted Platinum Carbon Black; Pentel Aquash with Platinum Pigment ink in Sepia; Pentel Aquash with water; mini Pentel Aquash; and the Pentel Aquash watercolor brush I previously reviewed.

This quick doodle is on Fabriano 90 gsm sketch paper, with the Carbon Black/Sakura waterbrush combination.

This is the Pentel Aquash/Sepia pigment ink – yes, the ink is that light.

These inks really do come into their own when used with watercolor, because they’re waterproof.

I liked this little hack very much. If you have a waterproof ink you’re bored with, try it in a waterbrush instead of a fountain pen and take it for a spin.
