The Head Team tennis balls are approved by the ITF (International Tennis Federation) and have constant seams and TexTech felt for enhanced durability. These pressurized balls are suitable for all court surfaces and offer a combination of control and playability. They are a great choice for beginners and recreational players and guarantee good all-around performance and a consistent bounce. The balls are easier to spot on the court thanks to a high visibility yellow colour. They are supplied in a pack of 12 dozen (144balls).
