  • Jar of 10 M sized bobbins


Magna-Glide is a pre-wound bobbin from Fil-tec using Glide, the 40 weight polyester thread you already know and trust, and wraps it 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.

Magna-Glides are produced using the top Glide colors, giving you a perfect match on the bottom and top of every piece you stitch.

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

    Love these! You can't go wrong with magna-glide bobbins. They work perfectly with Glide thread and take all the hassle out of trying to wind your own bobbins. They produce beautiful stitches. Just remember, because of the magnetic core to remove your backlash spring.
