Most tennis players, coaches and teachers will get through dozens if not hundreds of balls each year, and with balls replaced every ninth game in most professional tournaments, it's important to have lots of tennis balls to hand! If you are looking to train & practice with tennis balls that replicate the performance of the balls you'll use in regulation matches, you'll no doubt be interested in the multi-buy discounts that are available with our Vermont Classic Tour Tennis Balls. The pressurised, ITF-approved tennis balls with DuraCore centres & FluroFelt exteriors, can be purchased in multi-packs of more than 500 balls. We also sell buckets of 60 pressureless tennis balls, as well as bulk mini tennis balls for all developmental stages.
