This highly durable, woven tubing is composed of monofilament and mylar, giving it a vibrant, pearlescent sheen that perfectly imitates fish scales and is ideal for tying large freshwater and saltwater streamer bodies. The tubing is approximately 1/4inch (0.6cm) wide but can be pushed together to expand and create bulky, realistic silhouettes for baitfish, eels, shrimp, and squid patterns.
