Oventure Big O Silicone Key Ring

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 Inner Core - The rigid interior core helps the Big O® maintain its shape and long-lasting durability. The non-bending, anti-squish design means it can withstand everything you can. Waterproof Silicone - The Silicone Big O® can be washed with soap and water for a germ-busting, instant clean feeling. Non-Toxic Silicone - We only use the highest quality, non-staining silicone. Translation: If your teething baby gets a hold of it, not to worry.  One-Size-Fits-All Design - The oversized fit with a 3.75in diameter was designed to be worn on the forearm, or even over the elbow, so it’s comfortably out of the way.
