The Dunlop Intro Squash Ball is a black squash ball with a single blue dot. It is suitable for beginners and juniors. This ball is 12% bigger and has 40% more bounce than the official match ball (the Dunlop Pro Squash Ball). This makes it easier to keep the game going and you can easily play a rally. It is also an advantage that this ball does not have to be warmed up, so you can start the game immediately.
