Dehara Yukinori is an artist from Japan. Amongst other things, he makes designer vinyl toys. My personal favorites are the Menta-Kun and Chibi Menta guys (both available at rotofugi). I don’t know what they are, but they are adorable.
Something tells me there’s a vaguely disturbing explanation for what these guys are judging from Dehara’s other works. But I prefer to just think of them as adorable little veiny guys who sit on a shelf in my dining room and make me happy! haha.
