This translucent helical fiber changes the depth of tone from a deep virtually radiant hue that almost glows, to what appears as a lighter shade of the same colour with a frosty sheen, depending on how the light hits the material.This mimics the behavior of light playing on the skin of natural baitfish, simulating the changes of luster and colour that take place naturally.The resulting artificial, tied using Frosty Fish Fibre has an incredible life-like characteristic and tonal changes of the real thing.
