This is a set of impact tape designed for swing training, suitable for iron, wood and fairway golf clubs. Made with high resolution printing, it can clearly record the exact impact position of the golf ball on the club face. It leaves no residue after peeling off, so it will not damage the surface of your clubs. You can use these strike stickers in driving ranges, practice courses and home golf practice areas to help you analyze your swing angle and hitting habit, adjust your movement and improve your swing accuracy step by step.
