An adhesive bandage, also called a sticking plaster, sticky plaster, medical plaster, or simply plaster in British English, is a small medical dressing used for injuries not serious enough to require a full-size bandage. They are also known by the genericized trademarks of Band-Aid (as "band-aid" or "band aid" in Australia, Canada, India and the US) or Elastoplast (in the UK).
