My fave ever
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.

Love this! Sturdy and elegant
I have a small selection of jewelry pieces I wear but I needed something that would keep them all together in one place. This jewelry box is fantastic! And It fits two pairs of sunglasses on the bottom compartment. I like that there’s a little tab to help pull up the top part. It was actually a bit bigger than expected which is a good thing. And still small enough for traveling. The necklace tabs are sturdy and hold them in place. I’m very satisfied with my purchase.

Get Bejewelled
This box is very nice. It feels sturdy. The color is true to the product picture and the material feels nice. The size is as expected. This was a gift for a young woman; she loved it and that it was cute enough to "fill space" while also being functional.
