Double Dimple technology is used to maximize the grip power of the ball's surface.
It is a great ball. We play with this ball day and night. The “Double Dimple” of the BD2000/BDC2000 combines a better gripping power with a gentle touch.
Also, even if you play with the BD2000 / BDC2000 for a long period of time, the ball rebound and its performace are stable. We can use the Mikasa balls for a long time without any problems. This can be said for all the balls produced by Mikasa, but the ball quality seems to be more consistent from one ball to another.
It is important for players to know the ball when you are playing in matches, and Mikasa clearly provides consistent, great quality balls which are good for players.
