Sapeur and Masatoshi Hamada collaboration socks. Black, men's free size. I bought these for myself but never had a chance to wear them, so I'm selling them. These are definitely authentic, so please rest assured. I want to sell these, so please comment with your desired price. First come, first served. I will list these over the weekend, and if they don't sell, I will take them to a recycle shop on Monday, so please consider purchasing them.
