(Product Name) Soft No. 3 FRP (Carbon) Bat Black Cannon 4L (Compatible with rubber balls) (Model Number) BCT53884 (Size) 84cm, 660g average, 57mm diameter (Color) Black (1900) (Material) FRP (Carbon) I used it for about 3 months, but I'm selling it because I bought a new bat! * To avoid any trouble, I had a friend assess it, and they said it's in about 80% condition compared to a new bat. * This model uses a four-layer tube structure in the hitting area to efficiently create a trampoline effect. By incorporating a special rubber sheet between the outermost layer and the next layer, the bat flexes even more, quickly recovers, and enables powerfully fast hits. The weight is set so that any type of batter can swing through it properly. ↑ The principle behind the Black Cannon 4L's flight, which is compatible with No. 3 rubber balls, is that a special rubber is built into the four-layer tube structure in the hitting area, between the outermost layer and the second layer. This allows the hitting area to flex softly and greatly upon impact, instantly restoring and amplifying the rebound. It hits the ball strongly and quickly, and the lightweight design makes it easy to swing, creating ultra-fast hits. The Black Cannon 4L will assist all soft No. 3 (rubber ball) players with their powerful batting.
