The S-Biner KeyRing 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 one of the plastic S-Biners 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.
