NAIGAI soft ball. Offers a low bounce and increased distance for playtime with similar feel to a hard sphere. While the bounce height is reduced by about 15%, it reduces air resistance and increases distance by reducing its shape. With an increased impact value of approximately 1% and safety, the ball feel is closer to a harder ball. You can also use it with details such as the shape of the dimple and the shape of the seams, and the number of the seams.
