Play ping-pong without the table, and no way of losing the ball! Invented by 10-year-old inventor Alexander Xiong in Minnesota, you can clamp Door Pong above any door frame, be it in your kids room, a dorm room, or anywhere else. Door pong clamps firmly but gently, so it can hang anywhere, but won't leave a residue or mark. Box contains 2 paddles, and one Door Pong clamp and ball with string. Ages 6 and up. Choking hazard, keep away from children under 3 years.
