Thank you for viewing. This is a set of two brand new, unopened Danwing Cole Fluorocarbon 6lb fishing lines. This is fluorocarbon that is known to those in the know. I encountered this line about 20 years ago and found it to be a very good line, so I bought a large quantity and stocked it. I remember that an angler who was just starting out in bass fishing at the time, who is now very successful, also highly praised it. Although it is a new, unopened item, it has been in someone's possession once, so please understand that no claims or returns are accepted. The following is the product description: Elimination of color fading through a new special manufacturing method, 10% increase in strength, and a significant improvement in visibility through the adoption of a new color. While maintaining the outstanding flexibility of Wrap Wing Light, we have succeeded in suppressing initial elongation. This has resulted in the completion of a perfect light re-grind with no trouble, ultra-high sensitivity, and ultra-high strength.
