Useful
Color: Black
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.

I haven’t misplaced my keys since I bought it. I do wish it were a little heavier in weight but it gets the job done
