Sakura Koi Waterbrush Pen - Small (#2) Nib

Great water brush for travel watercolor sketching

I found these at Hobby Lobby, and being a lover of brush pens, snapped up a couple of different sizes. I loaded them with fountain pen ink for use as brush pens, but unfortunately, I found them far inferior to the Niji/Kuretake water brushes, or to the Pentel Pocket brush pen if a brush pen is what you want. The bristles originally had a sort of oily texture, and they just didn't have the proper snap and spring; when pressure against the paper bent the bristles, they would tend to hold the bend and not spring back gracefully, so the tip would drag around rather than floating in and out like a better-quality brush. It's hard to describe, but was very noticeable. The cap does fit well, and the compact size would be good for portability, but again, for a waterbrush, I recommend Kuretake instead.
