Material: fluorocarbon, from Japan's top fluorocarbon fishing line factory.
Perfect as your leader line. Good quality in a "dispenser" box that keeps things neat in the tackle bag.
100% fluorocarbon line has a light refraction index similar to water. It becomes virtually invisible under the surface. When using the SF fluorocarbon line, fish will focus on the bait and not your fishing line.
Waterproof, has the same strength, sensitivity, and handling characteristics under the water as it does dry.
Smaller diameters, superior quality, high abrasion resistance, low malleability, easy for tying knots. The line is very supple, and right off the spool, there's very little line memory.
