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. 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 as the key ring can hold dozens of them. No more fiddling with split rings or fumbling to find the key you need.
