A unique blend of synthetic, glass-like fibers with a larger amount of ultra-fine flash, UVR, and pearlescent fibers. Every color is carefully mixed from several shades and infused with a touch of perfectly black, metallic fibers that create a subtle silhouette effect. The flat shape of the fibers makes the blend pulse vividly in the water, and since it doesn't absorb water, the fly stays lightweight. Its translucent structure makes it ideal for tying small and micro imitations of freshwater and saltwater baitfish and fry, shrimp, and similar creatures. No other material needed: this blend alone is enough to tie an entire fly.
