Color: Pink
Hard to close while earrings are in the case. Decent size and easy to carry around. Good quality, looks good and helps me keep my jewelry organized.

Gorgeous Tiffany-Blue & Perfect for Travel
I absolutely adore this little jewelry case. I don’t have a huge jewelry collection, so the size is perfect for me. It keeps everything organized without being bulky. The zipper feels very sturdy and smooth — not flimsy at all. And for anyone who loves Tiffany’s blue… the color is almost an exact match. I can set it next to my Tiffany box and it’s nearly identical. It’s such a pretty, luxe-looking shade. Highly recommend.

Convenient
This is great to take with you if you’re going out of town. It’s easier to keep track of your jewelry. It doesn’t take up much room, but holds several rings earrings and three necklaces.

Compact space saver jewelry case
Color: Pink
This is a small but compact jewelry case. Love that it holds all your special items, and you can grab and go anywhere with it! Love the pink color and that it has a zipper to keep the jewelry from falling out .
