Keyring

A keyring is a ring of material, usually metal or plastic, that holds keys and other small items, which are sometimes connected to keychains.

The commonest format of a key ring is a metal ring consisting of two complete loops. Either end of the loop can be pried open to allow a key to be inserted and slid along the spiral until it becomes wholly engaged onto the ring. Often the ring is adorned with a key fob making identification easy and possibly also identifying the purpose of the keys.

Other forms of ring may use a single loop of metal or plastic with a mechanism to open and securely close the loop.
