The ABS HD is the latest ABS ITTF Approved 3 Star Seam ball from SANWEI.
Inherit the great quality from the legendary ABS PRO, the ABS HD is an upgrade version of ABS PRO.
The roundness is improved by another round of manual selection. And with the new formula, the ABS HD has longer durability than ABS Pro. ABS Pro can survive an altitude of over 2000 meters, the ABS HD can survive more!
