It's the same length as the mm23JR and the weight is almost the same based on actual measurements. The 82cm version is a bit heavier, which reduces head speed, so it's not recommended for those who have been using bats around 610g. The 80cm version allows for a faster head speed and is easier to swing. However, the distance it achieves doesn't match the MM23JR. It's recommended for those who can't afford the MM23 due to its price. * Limited edition, a remake of the MM18 custom order for juniors, focusing on thickness. * The thick urethane design makes it difficult for the ball to flatten on impact, allowing for greater distance by utilizing the repulsive force. * Heavy type for junior high school soft ball players. ■ Color: White ■ Balance: Top Balance ■ Length: 80cm ■ Weight: 700g ■ Made in Japan ■ 2025 Model Popular model/series...
