The round part is shiny, and I was surprised to see myself and the room reflected when I took a picture. I bought it for the design, so I'm sorry, but I can't answer your question about what it's made of. I don't know either. I had it stored away, so please understand that. I'm also selling other handmade and unused items. I have children's clothes in sizes 140cm to 160cm, so please take a look if you'd like.
