Used for about 3 hours in a doubles practice session from late September 2025 onwards. They are still firm, the logos are still visible, and they are still usable balls. How about using them for game practice or warm-ups? Besides tennis, they can also be used for chair legs, lower back pain, labor pain relief, massage, catchball, etc. *Please note that the bottom 4 balls in the photo were used in light rain, so they have some fuzziness. They will be sent in a case, but please comment if you don't need it. I will discount them to 1850 yen. #DunlopFort #TennisBalls #TennisBallsHardCourt #Srixon #Yonex #ChairLegs #LowerBackPain #FootMassage #Massage #LaborPains #DogToy #KidsToy #Catchball Type...Hard Court
