I ordered some "Sakura" pens, per the recommendation of an artistically talented student I work with, and for some reason the first thing I was inspired to draw with them were some vaguely Polynesian tribal masks.
I looked at nothing for reference, so they probably don't really look Polynesian at all.
I love the way these pens feel, though. Nice fine line, no bleeding, solid black pigment archival quality ink. :)
