Sharpie

In the USA, Sharpie often refers to a type of permanent marker manufactured by the Sanford company. While a Sharpie is a brand name, its widespread use has resulted in the use of "Sharpie" as a term describing any type of permanent marker, often black or red colored.

The marker saw national controversy in the United States in when American football player Terrell Owens used a marker to sign a ball in the middle of a 2002 game.
