I am selling this bat because I had it in stock in case of breakage, but I haven't used it. 【High-Quality Material】 This bat is made of FRP (fiber-reinforced plastic), which is lightweight yet boasts high durability. 【Appropriate Size】 The 80cm length and 690g weight provide an optimal balance for junior players, making swinging easier. 【Brand Reliability】 SSK is a trusted brand for baseball equipment and is used by professional players. - Brand: SSK - Model Number: SBB4037S - Size: 80cm (690g) for Juniors - Material: FRP - Color: 9020 Black/Red Thank you for viewing.
