Cute gift!
Color: A1 - Pink 1 Pack
Perfect to travel with or throw in sports bags. Purchased for my athlete college student and she keeps it in her basketball bag to take jewelry off before practice and keep everything safe and untangled. There’s a spot for every type of jewelry. It’s sturdy, closes and seals and if perfect!

Adorable, functional, and great for travel
Color: A1 - Pink 1 Pack
Adorable, good quality, small but fits enough for travel. I’ve had no problems with the zipper or any of the inside functions. I like that you can remove one of the pieces to fit something larger in it.

This was a gift for my teen daughter she’s collecting jewelry now and this was perfect for her. This is also great for traveling! It holds lots of little pieces and feels soft. This is a great gift idea. Months later and it’s still in great condition. Easy to use and take along anywhere.
