Softball 3-piece Mizuno Pro Bat Set: A X4, X, and Beyond Max Type: Bat A X4 is approximately 84cm, 680g X is approximately 85cm, weighs around 700g (Please check the weight details online) I am selling these bats because I am buying new ones. I used them today, and while there are some scratches from use, they can still be used at the forefront. Thank you.
