Each container of Cortland Fly Line Cleaner Pads has 5 pre-treated fly line cleaner pads. To quickly and easily clean your fly line pinch the fly line with the pre-treated pad between your fingers and strip the line through it. This helps the line float better and lengthens the life of the line. It also helps your casting and retrieving. Easy to carry in a pocket on your fly fishing vest.
