Cute
Color: A White, Color: A White
It's super cute and goes well with the decor in my room. Comes with a leather bottom and easy to put together. Only problem is that's is a easy to fall apart as well. If one side is heavier then the other it will be lopsided. Holds necklaces okay... if you have heavy charms on them they will fall off.

Disappointing
Color: A White
The plastic was a little cheaper than I thought it would be, and the whole thing was a little smaller than I was picturing, you aren't able to rest necklaces on it because it's too short. Unfortunately I got it as a gift for someone else so I can't speak to its longevity but it was a bit disappointing.

Adorable!
Color: A White, Color: A White
I'm not sure what I saw in Mt mind's eye when I ordered this, but this was not it. HOWEVER, this little deer can't be more than 3.5 inches long and with it's over exaggerated antlers it actually makes the CUTEST little jewelry tree. As you can see I put studs thru the holes where the pairs are in symmetrical spots, but as my daughter said "it's kind of awkward that they aren't closer"
But the studs I'll keep in place will be my least used, so it shouldn't be an issue.
This little tree is made of very lightweight plastic which snapped together easily, but a big part of me hopes to someday find one a bit larger, made of ceramic.
As my daughter said "it's by far the most creative one I've ever seen"

Not worth it
Color: A White
Cheap and flimsy, Fell over with my jewelry on it. Everything got tangled because eit wasn't spaced out. For anyone looking to buy it--dont. It may not be tall enough for your necklaces to dangle and not drag on the tray. However it is beautiful, would not buy again
