Great for simple jewelry
Color: Black
I’ve had it for some time now, it’s okay. Not the material I was expecting. It’s sturdy. It came with a few scratches, I did get a used one though. I recommend this product for simple jewelry for kids, and get something better quality for your more expensive jewelry.

Good for the price

Very cute, well made, it is plastic but it’s durable. Better than the higher priced item I was considering.

Useful
Color: Black
It works for a key holder, but if the keys are heavy, you may have a problem.
