The grip is being replaced from a guide grip to a normal grip. Since it's 30 inches, training is possible even in small spaces. Please purchase only if you understand that this is a used item. It weighs approximately 1.2 kg, about three times the weight of a standard 7-iron. The movement of the weighted club shaft can be expected to improve the flexibility of the arms, shoulders, and back for the entire golf swing. It is said that swinging it a few times a day will help you master the ideal swing and correct slices. Note: This is not designed to hit balls, so please do not hit balls under any circumstances.
