Izzo’s FlatBall are ¼-inch high disks designed to help you eliminate “thin” and “fat” shots. A regular ball is 1 5/8” in diameter, giving you room for error. Since the FlatBall is so thin, you can only hit it properly or else you will miss it entirely. When you hit it directly, it will travel a short distance making it suitable for indoor and outdoor practice.
