Thank you for viewing my product. This is a Furutech wall outlet cover. I was using it with the outlet that I am also selling. It was installed, but the number of times it was used is small, so there are no noticeable scratches or stains. However, please understand that no claims or returns are accepted. The center mounting screw is included. I am shipping items on Mercari in my spare time, so it will take some time to ship. If you are in a hurry, I will try to accommodate you as much as possible, so please consult with me. Thank you.
