Fluorocarbon MADE IN JAPAN, specially designed for making bottom lines, the YAMATOYO fluoro shock leader has a surface treatment that facilitates sliding through the rings and provides high abrasion resistance. Its flexibility ensures a natural presentation of the bait. The 4lb to 25lb reels are ultra compact and equipped with an elastic band, their small size allows them to be easily stored in a pocket. The diameters from 35lb to 80lb have a very clever velcro to prevent fraying. Excellent value for money.
