Description Aluminum alloy material, light and flexible, shock-resistant and more stable The two spheres are , reducing data tolerance, thus ensuring the stability of the sphere during rotation, prolonging the , and suitable for 1A/3A/5A moves. The ball arm gradually forms a Vinclination near the central axis, which reduces friction and makes the ball idle . The 10-ball U-shaped shaft adopts high-precision bearings to reduce the functional wear and tear of the yo-yo, and realize more fancy and action. Adopt secondary oxidation technology, exquisite process design, superior performance, matching PC top finger cover is a spherical shape specially challenging the top finger.
