Sybai Blend Angel Hair Red Black. A mixture of very fine Mylar® synthetic hair with 6" to 8" (15 - 20 cm) strands that is packaged in hanks. It doesn't absorb water, so large flies don't get heavier. Soft, highly mobile with a pulsating action. Excellent material for wings, tails and bodies. Adds lots of sparkle and glitter to any fly.
