UV Micro Floss Hot Spots
This is a new type of UV reflective fly tying thread that can be used as standard tying threads, as a body floss or as ribbing or to accentuate specific features of a fly.
Perfect for instance for micronymph hotspots, ribbing of Spanish nymphs (perdigones) or incredible tails.
The development of this thread was highly challenging with focus on the colors visibility under the ultraviolet radiation.
