Thank you. How about these for winter practice hitting? I washed all the balls, but there are black stains and signs of use. It's a waste to throw them away, so I'm looking for someone who will use them for batting practice. These are used soft baseballs for batting centers, equivalent to M-size balls. They cannot be used in official games. How about them for batting practice such as tossing and tee work? Inspection has been carried out, but please be aware that there may be dirt, wear, tears, and occasionally cracks. Packaging will be in 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.
