I don't even know what this little thing is, but I drew it. One of innumerable visual treasures from Kurt Hollomon's bottomless basket o' tchotchkes.
Brush-pens are funny. It's a brush, but it doesn't feel like a brush -- the water-soluble ink flows differently than india ink, and the barrel is all fat (I suppose this is normal on bamboo-handled brushes, but I ink with a skinny little #2 usually). In general, my brush-handling skills need improvement, but it's even harder to get a handle on the brush-pen.
