Professional WLX-3105 Trimmer Line Spool, 0.105 in Dia, 660 ft L, Monofilament

Your trimmer line should be replaced every season. Old line can be weak and easy to break. It can also wear down from cutting thick weeds or against hard surfaces, causing you to not be able to cut as well. With Arnold Xtreme Professional Line, you can cut up to 3 times more area than economy lines, depending on cutting conditions and type of trimmer head. Made of monofilament.
