You gotta love those Japanese. Check out these aprons, designed by a prison official and cut, sewn and assembled by inmates at Hakodate Juvenile Prison on the northern island of Hokkaido.

Featuring the Japanese character for "jail" inside the circle, with "PRISON" printed in English below, they’ve been a huge hit among the non-incarcerated fashion conscious, and are totally sold out on their website. It’s been so popular, in fact, that the prison is planning to register the logo with the patent office.

The prison is not allowed to hire more staff to meet the demand, and the inmates are forbidden to work overtime.

But like every other hot selling design out there, it’s only a matter of time until somebody rips off this design. Toss those bootleggers in jail, and there you go! Instant labor pool!
