Adhesive-backed lead tape. Use to shape weighted under-bodies for Zonkers and similar streamers. Package contains 1" x 2' length of tape, 0.2mm (0.008") thick. Warning: "Lead may cause cancer, birth defects and other reproductive harm." Do not eat, or eat fish that have eaten, flies that contain this material.
I like this product becasue it provides another option to weigh down your flies if you don't want to use beads or lead wire. Cut it in really thin strips to make wrapping it easier. It forms great caddis and scud underbodies.
