Nittaku rubber, Hammond (NR-8527), 2 sheets (1 red/thick, 1 black/thick) brand new. Emphasis on speed and excellent bounce! The concept of IE rubber is to minimize the loss of mechanical energy generated by the collision of elastic systems when hitting the ball, and to efficiently transfer energy to the ball. It catches the ball with the flexibility of natural rubber and powerfully drives it in the direction of the shot with the repulsion of synthetic rubber! It is truly a rubber that concentrates energy. The rubber is lightweight and easy to swing even with a thick sheet. ● Product Number: NR-8527 ● List Price: ¥3,520 (tax included) x 2 sheets = ¥7,040 ● Performance: Speed = 12.5, Spin = 10, Sponge Hardness = 30 Shipping included.
