The first and only tee proven in "Robotic and Field" tests to improve distance. The flexible, six prong tip reduces resistance and allows better contact with the ball. Very durable, lasting over 100 drives. This tee has been a golfing favorite since it's introduction. Choose the length you want, 1 3/4" for irons, 2 3/4", 3 1/4", 4" for drivers or try the variety pack (1 of each size). Each size tee has it's own color. You get 4 tees per pack.
