Compared to soft urethane bats like Tech Ace and Beyond, this is a popular junior model from the Hyper Mach series, offering superior lightness and feel. I couldn't get used to the mushy feel characteristic of Beyond-type bats, and while I used a carbon Black Cannon for casual baseball, I eventually settled on the Hyper Mach. The light yet moderately firm feel is exhilarating and recommended. My nephew used this for about a year, exclusively for games. It is a used item, but in good condition and still usable. (Cleaned) There are scratches and dirt from use. New ones cost tens of thousands of yen, so it's easy to try one out used. Feel free to ask any questions.
