Two drawer jewelry box
Color: Pink, Size: 2 Layer
Heavier than expected. Exactly as pictured. Two drawers. Seems like a good product. Packaged well. No unpleasant odor. Arrived on time.

“Stylish and Spacious Jewelry Box, but Quality Could Be Better”
Color: White, Size: 2 Layer
The Casegrace jewelry box looks elegant and feels durable with a nice weight to it. The interior is soft and well-organized, with plenty of compartments for rings, earrings, and other pieces. It’s great for keeping jewelry neatly arranged and easy to find.
However, the top cover isn’t real glass — it’s more like plexiglass or plastic — and it doesn’t lift open, which was a bit disappointing. The outer material looks nice but feels like it could start to wear or peel over time.
Overall, it’s still a stylish and functional jewelry box with good storage space and a clean look, but the build quality could be a little better for the price.

Top tier rotating jewelry box; soft and great quality
This has got to be the most functional jewelry box I’ve ever seen. It’s not very traditional in design and I love that about it. It stands vertically and rotates! Every side is designed differently and constructed to house multiple types of jewelry. I tried to snap a picture of each angle. I like that it has features to keep the jewelry organized too, like the necklaces or bracelets that can be hung on clips/rungs and placed neatly inside a pocket which kind of binds it into place and lowers the chances of it tangling.
There’s even a mirror that you can look into when putting your jewelry on. It seems like the box favors rings and necklaces more-so than earrings (which I have most of) but you can get creative and place earrings in the pocket that’s under the mirror flap or inside the drawer. This is definitely worth its value—it does not disappoint! 5/5:)

Perfect for my wife! Great quality and durability
I’m very impressed with this spinning jewelry box! My expectations were pretty high before receiving it, and I’m happy to say they were definitely met.
The materials used are top-quality and have a pleasant, fresh wood scent. The felt lining inside is incredibly soft and adds a touch of luxury. All the drawers open smoothly, except for the side ones, which are a bit stiff—my only minor critique. I wish they glided as easily as the rest.
Functionality-wise, this box is excellent. It offers plenty of space for storing a variety of jewelry pieces, and the spinning feature is smooth and effortless. After a few days of use, it’s been a completely enjoyable experience.
Overall, this is a beautiful, well-made piece that combines quality, functionality, and elegance. I highly recommend it for anyone looking for a stylish and durable jewelry storage solution.

Lots of storage for jewelry
So much more organization for my jewelry! It spends very easily and has plenty of storage. I like the large mirror on one side, the multiple earring holders as well as many necklace holders too. I really love how you can pull out the two pieces, that definitely adds more storage than if it was only a flat side. There's even a spot specifically for bracelets and watches. One of the sides actually has a cover you have to pull down, which I feel like gives it extra protection from dust or moisture, but has a glass window so you can see in. I like the smaller ring holder in that spot just because I don't own many rings. But I wish the one that holds the bracelets didn't have as many ring holders because that's not very useful to me. The other thing is it is very difficult to work my way behind the earrings to put the backs on, so I wish there was a way to take those out, put the earrings in, and then put them back.
There's also a nice little extra spot up top and clothes on all sides to store more things. So overall it is helping to keep my cabinet and vanity a lot more cleaner. The price for me is a little high though in my opinion.
