Kuretake Disposable Pocket Brush Pen - Fine

This tip is softer than the xtra-fine, and shows good variation for small written Chinese calligraphy. It's also perfect for putting pine needles on pine trees with my ink paintings. Wide enough to show the right kinds of variation for the needles, but thin enough to keep every needle sharp. I can watercolor right over it and there's no smearing or bleed thru. It's perfect for what I'd hoped to use it for.

I suspect this will also be quite good for the thicker outline lines for manga-style drawing as well.
