Losing your keys or wallet isn't a rare accident. Almost a quarter of Americans lose their house or car keys twice a week, and 60% of Americans have lost a personal item in the past year, with keys and wallets being among the most frequently lost items. The average person spends about 2.5 days a year looking for lost items – and this costs American households a combined $2.7 billion annually in replacements.

This is rarely a memory problem. It's a clutter problem. A loose set of keys jingling next to a bulky wallet is exactly what gets set on a counter, tossed into a bag, or left in a coat pocket – never twice in the same place because there's never just one thing to keep track of. This is the problem K-01 solves. By combining your essential keys and cards into one thin, secure piece that sits flat in a front pocket, nothing jingles, nothing bulges in a back pocket, and nothing is forgotten separately. One item, always with you, always in the same place – so you stop losing things not because you try harder, but because there's simply less to lose.
