I really didn't know what I was missing until I got a Kuretake #13 Brush Pen. Until today, I've only used the disposable felt-tipped "brush" pens made by Tombow and Faber-Castell. The Kuretake makes those pens feel like crap. There is a WORLD of difference. The Kuretake feels like an actual brush. It's soft. The tip gives. There's bristles! The disposable ones feel so stiff, I wouldn't even consider it a "brush" pen after using the Kuretake. I think the only advantage of those is that they're cheap and easier to control, but you loose that beautiful calligraphic look of a real brush. Anyway, if you're into brush pens, you owe it to yourself to get the good stuff :) I heard Pentel Pocket Brush is amazing too and cheaper than the Kuretake #13 that I have. Worth looking into.
I really like the very bold look of brush pen drawing. It's a bit scary though because re-stated lines don't look as nice on a brush pen drawing as they do in pencil. It's definitely for artists that have a brave streak.
Well, Hope you enjoyed my drawings!
Until next time!
