The J-grip function of this bat helps correct swing and prevent injuries. The rounded grip end is designed to be between a J-grip and a standard grip. Significantly improved hold. Expected to be effective in preventing injuries to the ulna and wrists. Swinging without feeling any discomfort naturally leads to an inside-out swing, and furthermore, allows for a "level swing" that enables you to hit the ball with a line drive. ● Material: Carbon composite ● Color: White & Green ● Size: 79.5cm, average 590g ● Semi-top balance ● For softball 2-gou (2nd grade) Good Design Award Winner I liked the exquisite length, balance, material, and unique hitting sound and used it.
