15 Pack (WA0010)Replacement Trimmer Line Spool C
This weed eater trimmer line is pretty tough. Although there was only 12 spools in the box, but the Description says 15 spools, And this trimmer line is a lot tougher than the previous line I was using. I used very little of it on the first spool, which is great these Worx trimmer line spools fit perfectly and function perfectly this is a great product to purchase, and I will highly recommend them. if you just have a small amount of weed eating to do I would recommend getting these spools for your worx weed eater.
