Magna-Glide Delights are the original high-yield magnetic-core prewound bobbins from Fil-Tec. The patented magnetic core delivers consistent thread tension from a full bobbin down to the last yard — no mid-project tension adjustments, no backlash, no over-spin, and no need for backlash springs. Each box contains 100 Black Style M bobbins wound with smooth 40wt filament polyester. The larger Style M size holds nearly twice the thread of a Class L bobbin, making it the go-to choice for longarm quilting machines and other machines that accept M-style bobbins. Fiber: Filament polyester Thread weight: 40wt, 2 ply Bobbin style: Style M, magnetic core Bobbins per box: 100 Length per bobbin: 132 yards Recommended needle: 65/9 (domestic), 4.0 (longarm) Use: Bobbin thread for longarm quilting, embroidery, and general sewing Magnetic-core bobbins keep delivery even as the bobbin empties, which is why longarm quilters rely on Magna-Glide for stitch consistency across large projects.
