Thank you. I wanted to deliver clean balls, so I washed all of them. How about using them for batting practice in the second half of winter training? These are used balls for batting centers, equivalent to M-size ball specifications. They cannot be used in official games. How about using them for batting practice such as toss and tee? Inspection has been carried out, but please be aware that there may be dirt, wear, tears, and occasionally cracks. Packaging is recycled cardboard. Please refrain from purchasing if you are sensitive to these issues. Please enlarge the photos, etc., and only purchase if you understand.
