It's a beautiful piece, it was delivered sooner than expected which it is a plus the only thing I noticed after opening package, the top of the stand was slightly bent, I don't want to try to fix it because I'm afraid it may break. Overall it is very stable beautiful jewelry stand. Not too big and not too small. Perfect size.
