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.
