Each spool contains 10 feet of string, and so each 4 pack we send has 40 feet of line. Trim and edge as much as you want, we’ll make more. This DoubleHelix line is only 0.065” thick yet has over 100 lbs of tensile strength. That thin diameter means it can be spun faster, and its solid construction tears through thicker grass.
