Designed by computer simulation, FREE CORE is an innovative form of handles made using nano-nylon materials and molding techniques. It allows players to move more freely, swing smoother, and gives comfort to the hand.

Combining the controllability of “diamond-shape” structure with the stability and smoothness of “sword-shape” structure, AERO-DIAMOND frame minimizes air-resistance and improves handling stability during each game.
