Idena Basic Tennis Balls Class A 3 Pieces is a ball for movement, catching, throwing, kicking, or water games. The quantity mentioned in the title is 3 pieces. Diameter, material, and weight determine whether the ball is more suitable for throwing, catching, kicking, or playing in water. Soft balls are ideal for initial catching exercises and reduce the impact when hit. Inflatable balls should only be filled to the specified firmness. After use outdoors or in water, the ball should be cleaned and dried. For indoor use, sufficient distance from windows, lamps, and delicate objects is required. The appropriate air pressure improves the shape and playing behavior. For foam balls, the surface should be protected from prolonged moisture. The surface should be regularly checked for cracks or significant deformations. The suitable surface depends on the material and surface structure of the ball. For initial catching exercises, a soft ball is easier to control than a hard sports ball. For inflatable models, the valve should be flush closed after filling.
