A quick look: the ZIG Cocoiro.
This was easy to dismiss as a cutesy pen until I wrote and drew with it.
Verdict? Not bad. Kalina, who tweets as @geminica, found it unpredictable in a review over at Pen Addict— that’s probably why I like it. I’ve yet to try the Tombow Fudenosuke.
The Cocoiro is a little adventure packed into a cute, curvy, soft body.
Drawing with it is a pleasant diversion from fountain pens. Not better, just different.
Have you played with the Cocoiro yet?
