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

Great for simple jewelry
Color: Black
I’ve had it for some time now, it’s okay. Not the material I was expecting. It’s sturdy. It came with a few scratches, I did get a used one though. I recommend this product for simple jewelry for kids, and get something better quality for your more expensive jewelry.
