Line Markers are designed and formulated for use on braided line with a notched tip for easy application. The long-lasting ink penetrates between the fibers and also coats the outside of the line to provide new color with no loss of performance. The line is ready to use in seconds after application. It works great for touching up faded colors, adding a new color or blends or for depth marking on the line. You can also use a mixture of colors to make a camouflage line. The UV-Glo version works great for night anglers using a blacklight for night visibility.
