Admit it, you have a drawerful of mystery keys, whose use is long forgotten, and you have no idea if you should keep ’em or toss ’em. You could go on tossing keys into that key graveyard forever, or you could start labeling ’em and storing ’em properly – so you’d know that random key you can’t identify is actually from the shed you had 16 years ago, before you moved across the country. The IdentiKey Card Storage System allows you to organize up to four keys in a compact, flat cartridge, easy for storing compactly anywhere. Durable, colorful write-on tags (included) make key identification simple. Simply write on the IdentiKey Tag with permanent ink, affix it to your key, and slide it safely into one of the integrated key slots in the card. The card can be hung or snapped together with another IdentiKey card to store up to eight keys together in the space-saving system. It’s the key to keeping keys organized!
