Key tags are plastic or metal tags attached to a split key ring. They are available in numerous colours and styles and are primarily used to help differentiate between keys.
Some plastic varieties contain a slip of paper that can be customised, written on and returned. Others have a space where a printed label or piece of tape will easily fit. This can help to identify similar keys from one another.
Key tags are also available with a printed or engraved number. These are commonly used in hotels, clubs, leisure centres and schools.
