Best Jewelry Box Ever!!
Color: White, Size: XL
I am so pleased with this lovely jewelry box. It is very sturdy and and extremely well made. To save a little money, I reluctantly chose my least favorite color white, but it turned out to be a great decision. I love the color. The jewelry box stands out very nicely on my dark wood nightstand. There is so much room for all my jewelry. In previous boxes everything was jumbled together and I could never find what I was looking for. Now all my necklaces, watches, rings, and earrings are perfectly organized. As a result I am wearing more of my pieces because they are so easy to find. I highly recommend this jewelry box.

Well made, lots of storage
Beautiful jewelry box. Well made. Need storage for my many necklaces and all my daily jewelry. Iusually purchase Songmics jewelry boxes also well made. Iwas hoping this would be as nice and it certanly is! Packaged very well also not a chance of damage in transit! This has all kinds of room to hold a lot of jewelry. I removed the watch rolls and earring holders. Love the lavender color.
