100% high quality and high strength fluorocarbon with uniform structure. We have created the ideal fluorocarbon reader for light games. It has excellent straightness, less thread swelling, high knot strength, and strong wear resistance against root misalignment. In addition, the combination with the high-sensitivity polyester line "Pinky" will bring out the surprising sensitivity. Although it is a compact spool that is easy to carry, it is a safe 50m roll.
