The Nite Ize KeyRing S-Biner features six different-colored, lightweight plastic S-Biners that attach quickly and securely to a sturdy, solid, stainless steel ring. It's easy to hang on hooks or loop through cord. Use a plastic S-Biner® to attach the whole unit to a second key ring, belt loop, purse strap, or zipper pull-anything with a loop or D-ring. The 6 plastic S-Biners the key ring comes with are perfectly sized to hold 6 separate keys, their vivid different colors allow you to identify your keys at a glance, and they attach and release from the key ring with ease. More S-Biners can be ordered separately-the key ring can hold many of them. No more fiddling with split rings or fumbling to find the key you need. The key ring is perfect for quick and easy sharing of keys with family members, co-workers, valets, babysitters, and for taking a single key with you when you're out on a run or ride.
