Special beach tennis balls with 50% compression. There are 3 pieces in a can.
Beach tennis balls have 0.6 atmospheres of internal pressure. Such reduced pressure makes it possible to deliver powerful blows to the opponent's side at close range. On the other hand, this pressure allows the receiving side to repel the most powerful attacks. The International Tennis Federation (ITF) has defined a special standard for beach tennis balls.
