Receive the power of core blanks. "I want Harris who can receive the power of Shimano rocky rods equipped with core blanks." To respond to that voice, we adopted high-purity fluoro. It exerts extremely excellent linear force and wear resistance, and it is difficult for the feeling of use and color to change over time. Although it is difficult as a manufacturing method, it is a high-purity fluoro, which balances transparency and hardness at a high level. Furthermore, since "soft winding" is adopted, you can enjoy the characteristics of the thread as it is. ● Succeeded in high purity while maintaining a balance between transparency and hardness. ● Straight line strength and excellent wear resistance. ● The feeling of use and color change over time are less likely to occur. ● By adopting soft winding, there is little winding habit and it does not interfere with Harris's original softness and strength. ● With line band where the thread stops anywhere Color: Clear Size (No.): 4 Length (m): 40 Standard diameter (mm): 0.33 * The color may look different from the actual product. Please be forewarned.
