Easy access from the wonderful design
I love this jewelry box!!! It holds sooo much and everything is easy and convenient to access with the spinning design!
Functioning: The designated hooks for necklaces keep them from getting tangled. The slide out drawers are easy to pull and I love that it has space specifically for bracelets or watches! I am thrilled with the holes to keep earrings together and pairs easy to grab, dangling or hoops work well on in the side area. All that is awesome , but pair it with the tray design on top to catch the jewelry I would otherwise toss on the dresser in a hurry and it's just a fabulous design.
The leather exterior is beautiful. I wasn't sure about it not being wood, but the quality is fantastic and I'm so happy I took the chance and got it!!! Well worth the price and would make a great gift!
