Damn, you need that shading?
No, I use it for chinese calligraphy.
Pencil is the only budget tool that can replicate brush strokes reliably.
They do make a fountain pen that also does that in japan, but it's one of those arm and a leg things. hahahahaha..
Brush pen is good, but it's only for writing much larger characters. I'm practicing at 1cm by 1cm.
