This is a set of two MUJI wooden bed frame connecting belts. These belts are used to connect and secure bed frames together to prevent them from shifting when using two beds side-by-side. I purchased these a few years ago and have stored them at home, having hardly used them. While I don't see any noticeable stains or marks, please understand that this is a used item and has been inspected by a non-professional. Available for immediate purchase.
