Good for the price

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

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

Novelty quality plastic, gorgeous color, and sturdy
Color: Purple
I was a little surprised when I took it out of the pkg. It seemed flimsy. It holds whatever I put in any position, perfectly balanced.
