This jewelry box is excellent and very convenient. It is made of sturdy material, which ensures its durability. It is very useful for storing all kinds of jewelry. It features space for 4 watches, at least 8 necklaces or bracelets, ample room for rings, and—one of the things I liked most—you can store your earrings without worrying about them falling out. The clasp is also very good.

Clean, classic jewelry box

Size: Large, Color: Apricot

This is the perfect size to go on my dresser. I used to have a tall jewelry chest that really just collected a bunch of things that I didn't really need. I wanted to downsize and just keep the pieces that are special to me and those that I wear often. This is a beautiful, simple box with enough storage for what I need. It has a clean, classic look and is built to last. There is a lock on the front, however, I have not used it so I can't speak to that. Overall, a great value and great piece to store jewelry.
