Cute jewelery holder
Color: C Blue
I was looking for something simple to hold some necklaces and earrings. I do the have much because I'm not much into jewelry but I didn't want to just sit them in a bathroom drawer. This jewelry rack is so convenient and doesn't take up a lot of room. Fits the bill just right.

Worth it
It was easy to assemble, now I have a place to hang my husband’s necklace, and organized other jewelries. For the price it’s very well made and sturdy.
It does not look cheap at all.
