Use this adapter with any standard batting tee to allow the batting tee to be used to hold just about any size ball! The adapter is made from a tough, flexible plastic. The big ball on a tee can be used in games and activities as a target to throw at and provides an entertaining way to build throwing skills in PE class, after school programs, and baseball programs. Just push the cylinder of the adapter into the rubber extension of your tee and you’re ready to play. Flip the adapters over and they can be used as mini cones or hold them in your hand and use them as a catch cup! Batting tees sold separately.
