The spools each hold 30 of string. I used that one for a Black & Decker Trimmer Edger. I am selling the trimmer in a separate ad for $12.00.
Works fine. Comes with almost a full spook of AF-100 string. The replacements come in 30 spools and WM sells them for 2 spools for just under $9.94. I m also selling 5 new replacement spools for $15 separate ad from Trimmer.
