The Muji Keybag is designed to save those with a propensity for losing their keys unnecessarily wasted time. The gadget is essentially a pocket that hangs from your doorknob.
The Muji Keybag was originally created for a design competition. Although the the Muji Keybag never made it into factories and shops, designers of the friends loved it, so a small series of hand made keybags is still being produced.
The designers are now looking for a company that will put the Muji Keybag into production to help others save time wasted searching for keys.
