The Penn Championship Extra Duty Tennis Ball is the # 1 choice of USPTA teaching pros. It features the exclusive fiber release technology for consistent nap. The natural rubber used in producing the Penn Championship Extra Duty Tennis Ball serves to provide a consistent feel and reduce shock. The ball felt consists of interlocking wool fibers that offer durability and longer wear useful on hard and abrasive outdoor courts. Cracking along the seams is also reduced due to the deep-elastic used in manufacturing this premier tennis ball. The Core Compound Technology utilizes a propietary blend of natural and man-made polymers to produce a core that limits ball softening.

This case contains 24 cans.
