It works so far lol!
Color: Apricotpink, Color: Apricotpink
I like it! I just packed it up with jewelry so when I travel with it (soon) I will update but my necklaces aren't snagging on each other so hopefully it travels well. It looks as good as it does in the pics and packs like a mini suitcase. It does get bulky, but that's because some of my jewelry is big and bulky so if you have flat jewelry it will lay down. I will have it on top so it doesn't get crushed, and will see if it travels well. It looks good and closes so we will see 🤞🏽!!!

Spacious and Well-Organized, Just a Bit Bulky for Travel
This jewelry organizer has tons of space and keeps everything neatly separated and easy to find. I love the binder-style layout and the zippered pouch for smaller pieces—it’s super functional and well thought out. The quality feels solid, and it holds a lot without tangling. My only drawback is that it’s a bit too large for convenient travel, especially if you’re trying to pack light. Still, a great option for home storage or longer trips where space isn’t as tight.
