This product covers the disadvantage of the standard fluorocarbon such as strains and hard memory due to low stretch and high sensitivity, and realizes high handleability. With its special soft processing, it maintains the natural advantages of the fluorocarbon such as high sensitivity and strength, and at the same time adds high-level softness and flexibility. It is not subject to peculiar winding and has distinguished conformity to the spool. The casting ability has also improved dramatically thanks to the consideration to guide friction upon casting. Also focusing on the abrasion resistance, it excels its power even at complex places.
