Love it
Color: White, Color: White
This is so beautiful! It's very good quality. I got this for my daughter to keep her jewelry in and it's perfect. It has three floors, the top opens for a ring compartment, and the sides open for necklaces. All the compartments have pink velvet on the inside. I really like the size of this, not too big but not too small. It fits perfectly on an over the toilet shelf or the bathroom counter. A great but with a decent price.

Beautiful Jewelry Storage
Color: White
A lovely jewelry box! Definitely worth the price. I love the little mirror inside, because it is useful when putting on my earrings. I do wish that one of the drawers was divided into smaller sections for bracelet storage, but overall the storage is amazing. Love the hooks for necklaces and the ring storage. It’s very pretty with the pink lining. Gorgeous for any space, and would make a lovely gift
