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.
