The Original Big O Key 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 patented, signature locking clasp clicks open and closed so you can contain your house keys, car keys, card case and more in one central, secure location.
Signature Locking Clasp - Our patented clasp was designed so we could swap our keys in and out securely, and without breaking a nail. (Epic win!)
Reinforced Shape - The Resin Big O® Key Ring is a non-bending, anti-squish design, which means it can withstand everything you can.
Water- and Stain-Resistant - The Resin Big O® can be washed with soap and water, or wiped with a damp cloth, for a germ-busting, instant clean feeling.
One-Size-Fits-All Design - The oversized fit with a 4-inch diameter can be worn on the forearm or over the elbow, so it's accessible yet comfortably out of the way.
