Z-Lon- Popularized by Craig Matthews many moons ago, this synthetic material was originally used for the tail on the ever so popular Sparkle Dun. It has superb, fish-attracting sparkle. Traps air bubbles for a lifelike look. Great for durable wing cases, spinner wings, shucks, and upright wings on parachutes. Assortment pack contains six strands each of white, medium dun, ginger, brown, olive, and cream. Made in USA.
