Details are unknown. Is it for surfing? I looked it up, and in terms of line capacity, it seems to be the same as Shimano's overseas versions of the Ultegra and Baitrunner 14000... Perhaps a spool from an overseas version of something... Please check the condition in the photos. Please consider this item as used. It will be sent via Yu-Packet Plus. The height is barely within the limit, so I probably won't be able to add much cushioning material. If you purchase this item together with other items and they can be shipped together, I will offer a discount. Yu-Packet Plus and Takkyubin Compact will be discounted by 400 yen. Items compatible with Nekopos and Yu-Packet will be discounted by 200 yen. I will discount for each additional item. Feel free to comment.
