Great travel jewelry case
Color: Black
Great colors. Good size. Easy to pack and carry. Fits a good amount of jewelry. It’s decent quality. I know there is better out there but for the value it’s great. It snaps close and I haven’t had mine accidentally come open at all. The inside is soft. My necklaces did get a little tangled inside but not too bad. I could have put them in there better. Very nice though.

Store it all!
Color: Pink
This is a compact, light weight, efficient, and sturdy/convenient way to securely store jewelry. The small compact case allows jewelry from earrings to necklaces to bracelets and rings to be all together without being tangled and/or on top of each other. I have more earrings than rings so I used the ring area to store the rest of my earrings. The tight clasp allows the lid to be fasten snuggly to the body of the case. The price was right considering what other stores were charging. I chose the pink case which is a very soft pink, as like the case, but there are other colors to choose from. The case is mobile and would stand strong in a carry on case or bag. I highly recommend this item if you are looking to organize and have your jewelry neatly and safely all in one place!

Cute and super convenient for travel
Color: Black
Really happy with this jewelry box overall. It’s compact, lightweight, and perfect for travel. The compartments are well designed for rings, earrings, and even long bracelets, which fit really nicely. The only downside for me is the necklace section. When using multiple necklaces, they can get tangled, so it’s not the most practical part of the case. Other than that, it’s a great product for the price and looks very cute
