Thank you. How about these for your upcoming winter practice? We've washed all the balls to deliver clean ones. These are used balls for batting centers, equivalent to M-size balls. They cannot be used in official games. How about them for batting practice, such as toss and tee drills? We have inspected them, but please be aware that there may be dirt, wear, tears, and occasionally cracks. The packaging will be recycled cardboard. Please refrain from purchasing if you are overly concerned about the condition. Please examine the photos closely and only purchase if you understand their condition.
