This is a kotatsu for pets from 3COINS. After purchasing it, I assembled it and tried to get my pet to use it, but they didn't seem to like it and wouldn't go inside. It's been sitting around for a while, so it's not unused. There are no noticeable scratches, but the top panel had a stain from when I bought it. The underside is clean. Please understand that it has been opened and used before purchasing.
