Magna-Glide Bobbins No. 60 - Lead Grey, also called Magna-Glide Classic, is a pre-wound bobbin from Fil-tec using a 60 weight filament polyester thread wrapped around their patented magnetic-core. This creates consistent delivery throughout the entire bobbin. No more interruptions for tension adjustments as your bobbin gets smaller. The magnetic-core prevents backlash or over spin and eliminates the need for backlash springs.

Due to differences in computer monitors and printers, the colors displayed above may vary slightly from the actual product. We always recommend comparing colors using your Glide Color Card.

For your Magna-Glide prewound bobbin to work accurately, always insert the magnet down into the case.

Remember to remove the anti-backlash check spring from the metal bobbin case prior to use. Failure to do so may lead to tension problems and thread breaks.
