It has the ultrathin "power spring body" produced of unique
materials, one of a kind in the world.

The body shell is formed of spring crown*and spring sole.
*At the moment of impact, the entire compressed body, sandwiched between the ball at
standstill and inertial force of the weight before and after, works elastically (= as a spring).
