Miniature 49 strand stainless steel wire that is extremely flexible and kink resistant. The nylon coating seals out water, prevents fraying, and makes the wire easy to knot. This wire is ideal for presenting life-like bait at any depth and can fool tackle-shy Billfish while withstanding violent razor-sharp strikes of King Mackerel and Shark. Excellent for casting flies and tempting the most discriminating toothy fish to the surface. Low elasticity and high sensitivity allow you to set hooks faster and with more accuracy. (Measures 16.4' or 5 meters in length)
