Keychain

Common card · No. 291691

A keychain ( ), also called a key chain or keyring, is a small ring or chain of metal to which keys may be attached. The terms keyring and keychain are often used interchangeably to mean both the individual ring or chain, or a combined unit of a ring and decorative or functional fob. The length of a keychain or fob may also allow an item to be used more easily than if connected directly to a keyring. Some keychains allow one or both ends to rotate, keeping the keychain from becoming twisted, while the item is being used.
