Glass Rattles are a great way to add sound to your flies. Big predators hunt by sound as well as sight and these rattles will help give you an edge. Pat Ehlers uses rattles in his Grim Reaper flies to imitate the clicking sound that crayfish make when moving their shellback. A tying tip, just tie these rattles in by the middle, don't cover the ends with thread so that they make more noise. 12 per pack
