Thank you for viewing! We decided to change the balls used in my circle! We chose Tecnifibre COURT "These!" from DUNLOP HD because of the feel and the quality of the felt (*^^*) These are used balls that were used for practice on an omni court as usual. Balls with deteriorated felt or extremely poor ball pressure have been removed, so I personally think these balls can still be used. (Some may feel like the pressure is reduced.) I'm not good at taking pictures, but there are very few balls that show wear and tear, such as the logo mark fading, and most of the 30 balls are like the ones in the photos. There may be some balls that have the string marks of the racket on them. 《Image 5》 These balls came in a package can like this (the package can is not included). There seem to be various uses other than tennis practice. I also use the balls I'm discarding for things like massaging my feet and lower back. It feels good (^^) 《Other》 There may be oversights such as dirt, but please understand that these are used balls. How about using them for tennis practice or other purposes?
