Professional tournament-grade material, durable and impact-resistant Microfibre Composite Leather: High-density microfibre leather, soft and delicate to the touch, as well as super abrasion-resistant, to withstand the friction of high-intensity training and competition. High elasticity inner liner: Built-in butyl rubber liner, airtight, long-lasting elasticity, quick rebound when hitting the ball, helping to control the ball accurately. Ergonomic design, upgraded feel 18 petals three-dimensional splicing process: 18 petals are scientifically spliced on the surface of the ball, which fits the curvature of the palm of the hand, providing a more stable grip, and a smoother power when passing and snapping. Anti-slip texture: Micron-level anti-slip particles are added to the surface to maintain a stable grip when hands are wet or sweaty, avoiding hand-off mistakes. Standard size and weight, suitable for competition International standard size: diameter 20.7-21.3cm, weight 260- 280g, suitable for professional games, school team training and adult competition. Uniform weight distribution: the filler inside the ball is uniformly distributed, the flight trajectory is stable, reducing deflection and improving the accuracy of passing and serving. Multi-scenario application, stable performance Indoor and outdoor versatility: the skin material adapts to wooden floors, plastic courts and outdoor sand, wear and tear resistance, prolonging the service life. All-weather performance: waterproof coating design, rain or wet environment can still maintain good elasticity, training is not restricted by the weather.
