Brand: ZETT Series: BLACK CANNON ZⅡ Model: BCT75878 Material: CARBON FIBER 3LayersSystem Description: The popular ZETT BLACK CANNON series, made with a 3-layer carbon fiber construction. Compared to the trendy urethane-based bats, it's light and easy to swing, and above all, the feel of the hit is solid, making it a recommended series for elementary school students. The grip was replaced once and used in rotation with 2-3 bats for about six months. It should be usable for a while longer. I purchased it used and used it for about six months when I was in the 4th grade of elementary school (height 130cm~140cm). There are many scratches and scuffs, but there are no scratches or damage that would hinder normal use. The BLACK CANNON series is generally a durable series. However, there are individual differences in how the condition is perceived, so please check the images provided. Shipping: Free shipping, scheduled to be shipped via Yamato's anonymous delivery service. If there is no suitable cardboard box, it will be shipped in simple packaging. Thank you for your understanding.
