Perfect!! I’m obsessed!
Size: Medium (6.8"W*4.4"D*2.2"H), Color: Beige
So cute and great for travel! Lots of organization areas, easy to use, very durable and not made cheap, the zipper closes just fine and it’s compact for traveling or storing under the sink.

Great little jewelry box for quick vacations! Lots of compartments so my jewelry doesn't get lost or tangled! Love the pouch for bracelets, the hooks for my necklaces, the little board with holes for my earrings and the slots for my rings. Made really well and pretty also! Would make a Nice gift!

Necessary for travel
Size: Medium (6.8"W*4.4"D*2.2"H), Color: Purple
This is really cute and looks classy. Quality is very nice. The only thing is the hooks for the necklaces didn’t keep them on, but everything else about this is a must for traveling and not losing or tangling up your jewelry.

LOVE IT!
Size: Large (8.2"W*4.2"D*2.4"H), Color: Beige
I love it. It’s very pretty and simple, in a good way. I plan to use it for all my jewelry and not just for travel. I like that it has a lot of hooks for necklaces and plenty of space for earring and rings. The fabric inside and out seem to be good quality. It’s well made and zips easily. The structure is sturdy as well. The color (white) is just as depicted. I think I got the larger size but it doesn’t feel bulky at all. I like that it comes with an extra pouch for bulkier items. It’s one of the best jewelry boxes I’ve had!
