Advanced Tennis Trainer Sparring Trainer With Rope

Features:1. Listening: The listening device is not called vacuum packaging, but is called high-pressure packaging. This air pressure protects the air pressure inside the tennis ball, so that the pressure attenuation of the tennis ball is much smaller before the opening of the cylinder cover.2. No pressure ball: This kind of tennis is supported by the bile. The air pressure in the ball is the normal atmospheric pressure, so the elasticity of this ball comes from the bladder rather than the intrabiliary pressure.3. Material: durable, wearable
Specifications:Color: greenMaterial: rubber
