Compact, sturdy, and fumble-free, the 2.8cm diameter Key Ring comes with 6 stainless steel S-Biners, to keep your keys secure, convenient, and easy to access. The Key Ring is a simple, handy, and secure way to organise and carry your keys. Its solid, continuous stainless steel ring comes with six #.5 stainless steel S-Biners that are perfectly sized to hold six separate keys, or use one to attach the whole unit to a second key ring, belt loop, purse strap, or zipper pull. The S-Biners remove and reattach quickly and securely, making it easy to share keys with family members, valets, babysitters, or for taking a single key with you when you're out for a run or ride. More S-Biners can be ordered separately; the Key Ring can hold plenty of them.
