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!

Nice little travel solution for jewelry
Size: Medium (6.8"W*4.4"D*2.2"H), Color: Pink
Cute travel box for my jewelry. The necklace hangers aren’t all that snug, causing my necklaces to fall and tangle some. But otherwise, works as expected.

I am very happy with this case
Color: A1 - Pink 1 Pack
It’s absolutely beautiful and practical. The soft pink color feels elegant and sweet, truly the best expression of romance. It’s compact yet spacious enough for rings, earrings, necklaces, and even a watch or lipstick. The compartments keep everything organized and tangle-free. Perfect for trips or daily use. I’m very happy with this lovely purchase.
