Review on Diamond Polishing Sandpaper Buffing by Liyafy by Marcus Cano

Very strong and durable sanding block. I've already used and cleaned them twice and they're still good enough to use a third time. I use the rough side of a blue dish sponge under warm water to remove most of the paint that has built up on the blacks and then let it dry. Many blocks don't stand up to such processing, but these do. I don't know how many more uses I will get from them!
