Thank you. We want to deliver clean balls, so we washed all of them. How about using them for winter practice? These are used balls for batting centers, equivalent to M-ball specifications. They cannot be used in official games. How about using them for batting practice such as toss and tee? We have inspected the balls, but please be aware that there may be dirt, wear, tears, and occasionally cracks. The packaging is recycled cardboard. Please refrain from purchasing if you are sensitive to these issues. Please enlarge the photos and only purchase if you understand the condition.
