I bought this to travel for a summer camp and still use it, two years later! It is now my everyday jewelry container. The gold clasp has held up well and closes well. Very easy to use and structurally sound! I love the color and overall vibe of it too- very straight forward. I use the top portion for long earrings, so know if you do that, it can be finnicky, if you have fun or funky shaped earrings- so just know they may get caught but it's such an easy fix. I would say it is about the size of half of an American Girl doll. Maybe around the size of half a goose.
