Wiz, the Japanese toy maker behind great stuff like the Flying Ultraman and the consolation money pocket calculator, today unveiled their newest stroke of genius, a mini USB construction site [JP, PDF].

As most USB gadgets, it doesn’t serve any real purpose (except for those Thanko makes, of course) but it looks kind of cute. Wiz says the main target group consists of male students aged 15 and up and stressed out salary men.

The construction site costs around $20 in Japan, is available in three different versions and goes on sale February 21. If you don’t live in this country and if you are interested in buying the toy, I suggest you ask this shop, this or this one.
