Easily transition from half court to full-court tennis with the Gamma Quick Kids' 78 Tennis Ball 12-Ball Bag. These beginner-friendly balls have rubber cores and polyester covers. They have a professional feel but are made to reduce the ball speed by 25%, allowing young players to learn the basics of full-court tennis in a slowed-down game. These 2-toned balls meet USTA and ITF stage 2 specifications for gameplay. Gamma Quick Kids' 78 Tennis Ball 12-Ball Bag Yellow/Green - Tennis at Academy Sports
