This is a plastic material. The glue dots that are included, aren’t enough to keep product together- so we had to use gorilla glue. The instructions weren’t very clear. The top didn’t fit well- we had to hammer it in place. Once together, very nice look. There is no lighting, so that causes a problem for the cat wanting to go in. I love the storage area. I haven’t gotten my cat to use it yet, but it is much nicer than having a litter box sitting out.
