Krystal Flash is a synthetic material that is commonly used in fly tying for both freshwater and saltwater fishing. It is a type of flash material that is made from a thin, flexible, and reflective material that is very similar in appearance to natural fish scales.
It is often used as a tying material for baitfish patterns and streamers. It can be incorporated into the fly’s body or used to create a tail, wing, or other components of the fly. Its reflective properties create a flash that mimics the natural flash of baitfish and other small aquatic creatures, making the fly more attractive to predatory fish.
Krystal-Flash is available in a variety of colors, and its reflective properties can be adjusted by changing the angle of the material in the water. It is a very versatile material and can be used to tie a wide range of fly patterns, from small trout flies to large saltwater patterns.
