Dunlop double yellow dot squash ball - the official ball for World Squash Federation, Professional Squash Association and Women's International Squash Players Association. Also used in all International Professional Competitions.
This Pro XX Double Yellow Dot ball tends to be the Dunlop ball that most club players will play with also. However, if you have particularly cold courts or want more hang time on the ball then the Dunlop Competition XT ball (single yellow dot) is a good alternative.
Balls tend to be single boxed balls but may also be provided in either plastic tubes or in card boxes of 3 balls. Packaging may vary.
