Fil-tec - Clear-Glide Poly Bulk Prewound Class 15A 135yd Bobbins Black - 80 Bobbins Per Set

No. 60 Filament Polyester. The ideal bobbin for domestic machine, Clear-Glide bobbins are wound on a plastic-sided bobbin shell. Because of this, they are not affected by humidity or oils. They are responsive to machine thread sensors so you don't have to worry about your yardage. Clear-Glide offers more stitches and yards per bobbin than both competitive and machine-wound bobbins.

Clear-Glide is a high-tenacity polyester filament bobbin wound on a plastic flanged spool. This bobbin is designed for home sewing (drop-in) machines. Clear-Glide uses the same high quality poly yarn as Magna-Glide and will provide the operator with more stitches per bobbin which results in fewer bobbin changes. Each lint-free bobbin provides uniform tension, and the plastic sides will not bend. Clear-Glide is available in style-L bobbins in white, black, and limited colors.  Fits most standard home drop-in machines (Style L). Works great with machine thread sensors. Plastic bobbin not affected by humidity or oil. No uneven tension caused by distorted paper sides. More stitches per bobbin, saves you time. Available in a wide range of colors.
