This is a set of two Irregui Marker Keimura Clear pens. These pens can be applied to various items such as lures, sabiki rigs, fishing hooks, and sinkers to increase their appeal. I've used other colors, and I felt they were effective because the fish's reaction was noticeably different during the evening bite. Thank you.
