The golf clubs are made with titanium for the driving distance of the ball. However, posture and theory is more important than driving distance for children. Furthermore, safety is the first consideration for children when playing golf. So why do we need to use titanium? With the focus on safety, the head is made with silicon. Safety is secured without any restriction on space when practicing swings by developing &＃39;foam (strength sponge) balls&＃39; to supplement for the demerit that golf practice needs a specific space due to the strength of the golf ball.
