Popular Model/Series...MM23 Material...Carbon/FRP Equipment Regulations Compliance...Youth Soft Baseball This bat definitely provides the most distance for youth soft baseball. I purchased it last December and used it until September, but I'm selling it because I'm going to play hardball baseball and no longer need it. Of course, I haven't used it in batting cages or for excessive hitting, but as you can see in the image, there are some cracks. Equipment checks are always conducted at the local and prefectural tournaments for the sports club, but I've never been warned about it, so I don't think there's a problem. My sixth-grade son, who used it, didn't feel that the distance changed. Finally, when my son used it with a long tee, he hit 80 meters, so I think there's no problem, but since it's a used item, please understand that it's non-refundable and non-returnable.
