The Babolat Initiation Orange mini tennis balls offer 50% of the pressure of a standard tennis ball and they are twice as slow through the air to deliver an optimal striking zone and allow more time for preparation. They give kids and adult beginners greater shot control and can be used on a 60-foot court (three quarters of a full court). These stage 2 balls support the International Tennis Federation’s "Tennis Play and Stay" campaign that aims to ensure all starter players can serve, rally and score from their first lesson. The balls come in a 3-ball tube.
