A standard paper football, with keys and key chain for size comparison.
Paper football (also called FIKI Football, Finger football, Chinese football, Biren football or Flick football) refers to a table-top game, loosely based on American football, in which a sheet of paper folded into a small triangle is slid back and forth across a table top by two opponents. This game is widely practiced, generally by boys of primary and middle school age in the United States, as an informal recreation.
