Dunlop Fort tennis balls are approved by the Japan Tennis Association and the International Tennis Federation, and are used in many tournaments in Japan. Since new cans are opened every weekend, there are differences in condition. Used only on omni courts for a few months, only on weekends, so there is little felt wear and many have clean mark printing. These were used in a tennis circle until this week. I think they can still be used for tennis ball machines, serve practice, baseball toss batting, playing with children or pets, stretching, covering chair legs or goat horns, etc. They will be shipped in a recycled cardboard box via Mercari delivery. Instant purchase is OK. Please refrain from price negotiations. #tennisballs #Dunlop #baseballpractice #petplay #balls #stretch #massage #goats
