Ping Pong(R), Nerf style(TM). The modular 4 piece net, which is actually 4 solid plastic connectible grids, can be set up on just about any table top, using only as much net as needed for the size of the table. The game can be played in very small spaces. The balls are Nerf foam, the paddles are relatively soft plastic, but stiff enough for the purpose of hitting the Nerf balls.NERF is a trademark of Parker Brothers.
