Textreme Crystalflash Solid Medium 0.37 mm is a brightly colored metallic twisted Mylar tying material designed to add shine and attractiveness to artificial flies. Used in streamers, ribbing or as a decorative reinforcement on bodies, it creates intense reflections that trigger fish attacks. Widely used for shrimp imitations for sea trout or bonefish, it also remains a must for Clouser Minnow and many tank models. Although less flexible than other materials, it ensures excellent durability and retains all its brilliance even after long immersions. Packaged in 300-strand bags, it's a sure bet for riggers looking for strong, bright fibers.
