If you don't already know what this table design is...then you probably shouldn't buy it.  This table pays tribute to the most celebrated plant in the world...marijuana!  The table is made from a lightweight yet durable aluminum that will keep your table in good shape but still allow you to easily bring it anywhere.  When opened, our Premium ProPong beer pong tables are 8 feet long, which is regulation tournament sized.  This beast folds up into a 2ft by 2ft briefcase to be carried where ever you'd like to play beer pong.  Those black triangles are there to keep the cups from sliding around or falling off the table, and if you look underneath the table you'll find a ball holder so you don't have to worry about lost balls at your next party.
