Pitsco has developed a peg for game-type projects. It may be used for the jump-a-peg game, tic-tac-toe, and even checkers. Now, there are no more problems with students poking each other or upholstery with golf tees! Overall length is 9/16", top is approximately 1/4" diameter, and post diameter is 1/8". The top of the peg has a hole that allows for the pegs to be stacked on top of each other.
