This is a great little jewelry box. I don’t have tons of jewelry right now, so this fits everything well, and the leather-look material is very nice. I like the simple design and organization, and it is a nice size to travel with. It looks really pretty sitting on my dresser and goes with the aesthetic of my home well.

Very nice simple jewelry box. My only issue is spacing to put necklaces is a bit tight, but there is plenty of room in this little guy. I put a lighter next to it, for size comparison.
