The Nite Ize Keyrack Locker S Biner is a supremely functional and delightfully colorful way to hold, organize, and secure your keys. Its high quality stainless steel carabiner clip has a secure gate closure on one end, allowing you to clip your keys to just about anything. The other end holds six brightly colored polycarbonate S-Biner MicroLocks, each one with the ability to hold up to three keys, and lock them securely in place with a simple twist motion. This tricky little design allows you to identify your keys by color, and to detach them individually from the KeyRack as needed.
