The lip plate, also known as a lip plug or lip disc, is a form of body modification. Increasingly larger discs (usually circular, made from clay or wood) are inserted into a pierced hole in either the upper or lower lip, or both, thereby stretching it. Archaeological evidence indicates that labrets have been independently invented no fewer than six times, in Sudan and Ethiopia (8700 BC), Mesoamerica (1500 BC), and Coastal Ecuador (500 BC). Today, the custom is maintained by a few groups in Africa and Amazonia.
