Not all fluorocarbons are created the same. To produce the perfect fluorocarbon you have to start with the best raw materials attainable, which is the foundation for our new Shinsei fluorocarbon. By using the purest, cleanest fluorocarbon crystals available we have produced the most invisible fluorocarbon on the market. After spending a tireless amount of hours in research and development with a team of Japanese engineers we have developed the perfect combination of strength, stretch and durability. The end result is a product which will absorb shock, while having the attributes needed for tying the perfect leader, or creating the ultimate top-shot. Whether you’re fishing for huge tuna or stealthy steelhead Shinsei is the clear choice for leader material. Available 2 -60 LB Test 25 meters/27 Yards.
