Used for about 3 hours in a doubles practice session after November 8, 2025. 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, catch, etc. They will be sent in a case, but please comment if you don't need it. I will lower the price to 1950 yen. #DunlopFort #TennisBalls #TennisBallsHardCourt #Srixon #Yonex #ChairLegs #LowerBackPain #FootMassage #Massage #LaborPain #DogToy #KidsToy #CatchBall Purpose: Hard court
