Good quality storage and display box
Color: White, Size: 2 Rolls
It holds many bracelets and seems to be well made. I like the easy removal of the cubes. My only regret is not ordering the larger one! This is a great way to store my bracelets and watches in a protective case, free from dust. I recommend this.

Very nice bracelet organizer
Color: Black, Size: 2 Rolls
This is a great jewelry box for holding bracelets and watches. Easy to open and holders are easy to remove and replace. I especially like the see-thru lid: keeps dust off bracelets and makes it easy to see what's in box.
