Key Bangle

Wear a locker or house key on the wrist

A flexible bracelet for the locker key: slip the open cuff over your wrist and hang the key ring on the tab, so the key stays on you in the pool, at the gym, on a run or on the beach instead of in a pocket you do not have. Print it in TPU so it springs round any wrist.
