Spinner strips are the little brother of Tiger Strips. Three layers of 1mm foam are secured by adhesive. Then cut into thin strips yielding a flat tri-color strip of foam with gray on the outside and a hi-vis color in the middle. Ideal for tying the foam wing case on our hackle spinners, these foam strips add incredible buoyancy and visibility to this great spinner pattern. We have tied with these strips from size 16-20.
