Impressed. This is a nice case. You can slip the bracelets on without any fuss. While I haven’t finished filling this one, I’m already considering a second case for watches and ankle bracelets. It’s convenient to see your items rather than digging for them. Nothing gets tangled either. There’s room for storing additional items below the two display rods.

Perfect little jewelry box
Color: Beige, Size: 2-Layer
My daughter loves this jewelry case. Her necklaces store nicely as it has a little pocket to secure the length of different pieces. She likes the modern color and style of the little hardware. Great quality for the price!
