1.INVISIBLE REALISTIC LURE:The fluorocarbon leader line is almost invisible underwater, allowing you to present your bait to the fish without scaring them away. The realistic appearance of the bait increases its effectiveness. 2. abrasion resistance: designed to withstand the abrasive teeth of large fish. The fluorocarbon line provides durability compared to conventional monofilament lines. It protects your main line from damage and ensures longlasting performance. 3.STRONG FLEXIBLE Unlike stainless steel wire, the fluorocarbon fishing wire is softer, stronger, and more resistant to bending, tangling and deformation. It acts as a shock absorber and counteracts the pulling force that occurs when hooking a fish. 4.Fast Sinking Sensitivity The fluorocarbon leader line sinks quickly, allowing you to reach the desired depth efficiently. Its water cutting ability ensures performance. In addition, it allows you to detect even the smallest bite.
