I bought these at a sneaker shop in Tenjin last year, but I forgot the name. I mainly wore them while working at a drugstore, so they don't have stains like you'd find in a restaurant, but I've used them quite a bit. I think they go well with techwear and also with more avant-garde fashion. I think they'll become quite clean if you wash them. I threw away the box, so I don't have it.
