Kinda Cheaply Made
It is super cute and could hold a lot. It is super light so it's not very sturdy. It is good for a temporary jewelry holder, but I am definetly going to get a different one.

Amazingly versatile
Color: E Black
Fun! It is really beautiful and easy to use. It is just about as big as your elbow to your fingers. It is great for necklaces and even bracelets and rings! It doesn’t shake unless you hang heavy necklaces on it. It is really stable otherwise though! It’s really easy to hang on the hook. If you have a clasp necklace, all you need to do is clasp it and put it on the stand. I’m amazed by the different types of jewelry you can put on, you can even put earrings on there but they might get lost so I don’t. Other than that so awesome!

Exactly what I was looking for
Color: Black Frame
I wanted to get something to help organize my everyday items without looking too tacky. I love the simplicity and sleek design. The dividers allow me to section off certain items while keeping everything in one place. The quality of the materials look and feel sturdy with an elegant touch.
