It is really well made and perfect for travel!
It is just like the picture and it is lovely. Plenty of room and under the tray it is large enough for changes with pendents. It is perfect for a girl and will be perfect for the amount of jewerly you take when traveling. Thank You!

Very nice little box.
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.
