- 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.
- Free Returns and Exchanges - The Big O® Key Ring is as amazing as they say, but if it’s just not your thing, we offer free and easy returns and exchanges.
