※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 images for installation examples. The stopper acts as a brake when slid outwards. It doesn't lock down completely, 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's a relatively similar screw. ※Stopper color: Gold ※Spool stopper screw color: Silver Please check in the comments before purchasing, as there may be stock shortages. We plan to ship via Yu-Packet Post Mini.
