Excellent organizer
Color: White, Size: 2 Layer
I wanted something to help me with the jewelry I keep in our safe and this works perfectly. I had kept items in their individual boxes, having to open each one to find what I sought. No more. I keep my more popular items in the top tray and I can see them through the glass. Next order items are in the lower drawer and easy to see many at once. The compact size lets it sit in the same form factor on the shelf in the safe. I’m very pleased with it.

Two drawer jewelry box

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.
