※Please note that this product is not an official product, but a substitute or general-purpose item. This is a stopper for the Battle Field Kurodai reel. ※Please check the images for the installation example. 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, etc. ※The stopper color is gold. Please check availability in the comments before purchasing, as it may be out of stock. We plan to ship via Yu-Packet Post Mini.
