This is the perfect size! I received my order sooner than expected when the first one wasn't delivered.

Not functional
Tree part is very cheaply made plastic material and does not fit well into the stand at all

Don’t bother, not worth the $
Much smaller in person than it appears. Looks more like a piece of coral than a tree. I got this to display some ornaments for sale at craft fairs, but it’s so small, it looks silly with the ornaments on it. Super flimsy, made of cheap plastic. Definitely not worth $14. Will be returning.

Cute
Just as described, perfect for putting rings and bracelets on. I put lines on the branches to resemble a birch tree . Its good value for the money
