This is a Yanase BFJ-certified hardball wooden bat! It can be used in official games! It's new and unopened, so there are no breaks or cracks. I'm hoping to sell them individually, but sets are also possible. (※Discounts will be applied for sets.) Natural wood Yanase Regular price: 20,000 yen (excluding tax) 86 cm, 900 grams or more, mid-balance! It's a pack knob bat, which is popular in the majors, etc. It's a type similar to a barrel bat. The tip is hollowed out! I welcome your comments with price negotiations and questions about the bat! Also, regarding the number of days until the item is shipped, I have set it a little longer because my availability varies depending on the day. Thank you for your understanding.
