Very nice for the price
Color: Jelly Pink, Size: 8"W, Color: Jelly Pink, Size: 8"W
This is a very nice jewelry case, especially for the price (around $10). I want to note that it is top heavy; even without the mirror inside the top part it tips over (won't sit flat on the bottom part when open, most of the time). There are some minor imperfections in the case, but nothing that will prevent it from doing its job and it still looks really nice. The necklace pocket does not have any dividers, it's one pocket. The zipper tabs look like they were painted, I'm not sure what material is underneath, but I'm hoping it does not chip over time. The stitching on the case looks nicely done.

Perfect for travel. Sturdy and will keep your items safe.
Color: Cloud White, Size: 8"W, Color: Cloud White, Size: 8"W
This was a galentines gift for a gift exchange. It comes with multiple compartments that are removable and can hold any type of jewelry from studs to necklaces, rings and bracelets. Any solid bracelet takes some maneuvering to hold. This is semi customizable to fit your needs and will house most jewelry items. The zipper does get stuck a bit but is a strong thick zipper and not super flimsy. The inserts on the sides can be removed, however, the ring inserts seem to be glued down. Bigger jewelry or chunky jewelry pieces may not fit well in this travel case. All in all it can hold quite a bit, the size is compact and perfect for travel and it’s a handy organizer for jewelry.

Economical Storage Solution
Color: Jelly Pink, Size: 4.6"D x 5.2"W x 2.8"H, Style: Upgraded Book Design, Color: Jelly Pink, Size: 4.6"D x 5.2"W x 2.8"H, Style: Upgraded Book Design
I needed a storage solution for some pieces that I wanted to keep in a small safe. This works great. Also, perfect size for travel. You will not be able to use all of the earring holes for adult size jewlery. But that’s okay. For the price point, you can buy multiple.  Tangle resistance: Price!

My fave ever
I bought this to travel for a summer camp and still use it, two years later! It is now my everyday jewelry container. The gold clasp has held up well and closes well. Very easy to use and structurally sound! I love the color and overall vibe of it too- very straight forward. I use the top portion for long earrings, so know if you do that, it can be finnicky, if you have fun or funky shaped earrings- so just know they may get caught but it's such an easy fix. I would say it is about the size of half of an American Girl doll. Maybe around the size of half a goose.
