cuffs
A band typically of leather and/or metal that fits around the wrist, arms, legs, or ankles of a person. These bands are typically used to restrain the wearer by linking the cuffs together by chains or metal rods, or by linking the cuffs to a wall or object. Highly associated with bondage.
For distinctive fabric cuffs at the end of sleeves, use sleeve cuffs. For decorative bands or what looks like detached sleeve cuffs worn around the wrist use the wrist cuffs tag.
The term cuffs is also slang for handcuffs, but for tagging purposes the handcuffs tag should be used only for images depicting the metal handcuffs used by the police.
