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! 24 pieces per package.
Other Details
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. There is a small dimple around the hole to reduce contact with the hook eye and bead and facilitate spinning.
