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 .

Great for travel
Got this for my wife to use on a trip, this thick cushion makes it feel safe and has a simple look to it but is still nice. Only one zipper so can't really lock it but it's small enough to where you can fit it pretty much anywhere with a lock already
