Clear-Glide embroidery bobbins are the sister product of the very successful "Magna-Glide" bobbin. 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.
