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

Stylish way to stay organized!
Color: Black
This tray is a perfect way to keep your everyday items organized and easy to find when you are getting ready for your day. No more wondering where you've put your keys, your glasses, your wallet, your watch or your every day wear jewelry like your wedding ring (if you have to remove it at night due to hands swelling or similar). This tray allows my husband to be ready to go quickly if we decide to spontaneously go somewhere. Its compact enough to fit on a night stand or a dresser, but still provides adequate spaces for your every day pocket items like a multi-tool or pocket knife, spare change, etc. Its well made and stylish too. I am very pleased with this purchase.
