I researched all the options I could find before deciding on this one. I wanted to gift this to my mom since she travels a lot. I was very pleased when I saw the high quality of the zipper. The zipper is nice anyway because many other options only have a snap, which is less secure/sturdy. It zips smoothly and doesn't get caught up or snagged. This case is roomy, and could fit quite a bit of jewelry! My mom used to use a soft side case, and this one will protect her jewelry better (especially since the necklace section keeps them from getting tangled up), and the pieces won't slide all over each other in transit. Overall, it is a well-made case that looks and feels nice, and will keep my mom's jewelry well-organized and protected. I just ordered another one for myself! :)

Practical Jewelry Box

Color: Black, Size: Medium - No Mirror

I really like this little jewelry box — the black PU leather gives it a classy look. It’s the perfect size to keep on my dresser at home, but it’s also super convenient for travel. The two layers make it easy to separate earrings, rings, and necklaces without everything getting tangled. It feels well made, zips smoothly, and keeps my pieces organized whether I’m at home or packing for a trip. Such a practical and pretty find.

Great gift

Color: Black, Size: Medium - No Mirror

Great gift. My sister loved it for traveling for long trips to bring lots of jewelry, keep it organized, and not take up a ton of space. Small blemish on the inside when she opened it but otherwise good quality and looked nice!
