Thank you. How about these for winter practice? We've washed all the balls to deliver clean ones. These are very popular Kenko quality A+ balls. Sorry for the high price. We are confident in the quality, so we've included close-up photos. There are some variations in the remaining groove condition, but the condition is very good overall. These are used balls for batting cages, equivalent to M-size balls. How about them for batting practice like toss and tee? They cannot be used in official games. We have inspected them, 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 overly concerned about the condition. Only those who can understand from the photos, please. Type... Balls Sport...
