2. The refractive index of light is very close to water, so it is not easy to
     be found by fish in the water.

3. The specific gravity is large, so it can sink quickly. 

4. No water absorption, so it is durable and has good water cut.

5. The elasticity is smaller than nylon, so the transmission of fish information is       sensitive. 

6. It has toughness and is not easy to curl. 

7. Using FNT (Flexible Non-Twist) manufacturing method, with unique dual structure technology,the knot of the fishing line is realized, so that while maintaining the strength, it can effectively wind the fishing line, knot strength, stretch, and impact resistance. The shrinkage of the fishing line, such as flexibility and flexibility, has been improved to make it a perfectly balanced fishing line that is flexible and easy to use.
