Thank you for viewing. ※Price is not negotiable. These balls were used at a batting center. They are worn overall, so they cannot be used in a batting machine. However, they can be used for batting practice and fielding practice. We inspect the balls, but in case there are any cracks, we will include a few extra. (The type of spare balls will be random.) We are looking forward to your purchase if you understand that these are used items. Used softballs, practice balls, team practice, youth softball, grass baseball, individual practice
