※ Please note that this product is not an official product, but a substitute or general-purpose item. This is a substitute screw for the Battle Field Kurodai stopper and spool stopper. ※ Please check the image for the installation image. The stopper acts as a brake when slid outwards. It is not rigidly fixed, so you can still release line while braking, making it easy to change rigs. The spool stopper screw is only a substitute. The color and base size may look slightly different, but it is a relatively similar screw. ※ Stopper color: Gold ※ Spool stopper screw color: Silver Please check in the comments before purchasing, as there may be stockouts. We plan to ship via Yu-Packet Post Mini.
