Fly Propellers are a simple way to add noise to your bass flies, pike flies and muskie flies.
These propeller blades can be placed between the hook eye and a bead head or cone head to add flash and sound to a fly. Try it on wooly buggers and leeches!
The length of the propellers (from tip to tip) is 3/8" for the small size, 9/16" for the medium and 11/16" for the large.
Try both colors the fish might like one on one day and not the next.
