Furniture Design Doorknob Key Holder by Denny Liao Doorknob is a playful wall mounted key holder that looks like an actual doorknob. Hang keys by inserting one key into the key slot. The slot is designed to fit with the key shaped keychain, as well as any other generic house key. The spherical knob doubles as a coat and hat hook. The idea is inspired by the funny moment when the designers couldn't find their keys, and realized that the keys have been hanging on their doorknob the entire time. The project started in 2013, and was showcased at the First Things First exhibition in NYC in 2014.
