Collection: Big O® Key Rings

The Big O® Key Ring is the patented original bracelet keychain — a bracelet-style key ring created and patented in Dallas, Texas in 2012. Its oversized design slips easily over your hand and rests on the wrist or forearm, keeping your keys close and your hands free. The locking carabiner-style clasp clicks audibly closed so everything stays secure. Over one million sold worldwide.

All three keyrings use the same patented design and locking carabiner-style clasp. Silicone is waterproof and easy to wipe clean, available in 50+ colors — best for active, everyday use. Resin has jewelry-inspired shimmer and shine — best for a polished, elevated look. Genuine leather comes in croc-embossed, snake, ostrich, and smooth textures — best for professional settings and gifting.

The Big O® Key Ring anchors the Oventure Hands-Free System. Clip on a keychain wallet or ID case for cards and cash, a silicone pouch for small essentials, and the Hook Me Up™ Phone Connector to carry your phone, keys, phone, wallet, and everyday essentials all in one place on your wrist.
