Why pay for precut string when you get more for your money and cut the string yourself.
I have a Craftsman Trimmer with a head that uses single precut line it can accept two sizes of line. This Red line gives you a clean cut for normal trimming. I also have a heavier Black line for heavy cutting of weeds. By buying in bulk rolls instead of precut it saves you money.
Good durable line for weed eater.
Just wish there was some kind of recurring marks on the line to indicate length. Like a dark mark in the plastic every 6 inches.
