Functional jewelry box with nice see through top.
Color: White, Size: 3 Drawer, Color: White, Size: 3 Drawer
Lovely jewelry box at the right price. I got this to match the corresponding rotating jewelry box here on Amazon and they look really nice next to each other. I didn't get to fill this up yet but I will update when I do if I need to add anything. The drawers are roomy and will hold a lot. I like the design of the see through top so I can see what pieces I have and use them more hopefully. It's not glass it's plastic and it's not the highest quality jewelry box but it does the job. I love it.
