Set of red and yellow plastic clips that fit on the grip to properly position the right and left thumbs when learning a grip.
Easy to apply or remove and simple to use. If you are a pro, you can place your hands on the club, adjust the clips, and then hand the club to your student so they can feel your hand placement.
Note: These are a little loose on kids clubs so they are recommended primarily on standard sized grips. May be used right or left-handed.
