As functional as it is fabulous, the Silicone Bamboo collection puts a fresh spin on the classic O-shape. The Silicone Bamboo O Ring is a one-size-fits-all bracelet key ring that can be worn on your forearm or above your elbow for hands-free ease. The locking clasp clicks open and closed so you can contain your house keys, car keys, card case, and more in one central location!
