Magna-Glide Delights Size L Prewound Bobbins - 40 wt Polyester - Jar of 20

Say goodbye to tension adjustments and uneven bobbin runs with Magna-Glide Delights Size L Prewound Bobbins by Fil-Tec! Packaged in a reusable clear screw-top storage jar, these patented magnetic-core bobbins deliver uniform thread delivery from the first inch to the very last yard.

Each bobbin is precision-wound with high-tenacity 40wt polyester thread matching Glide colors and features Fil-Tec’s patented magnetic core. The magnetic base adheres lightly to your bobbin case, preventing bobbin backlash, over-spinning, and annoying thread tails when stopping or changing sewing direction.

Why We Love It

Prewound bobbins are packed with up to 30% more thread than a standard self-wound bobbin, meaning fewer bobbin changes in the middle of quilting lines or bag construction. Because the tension is wound with factory precision, your stitches stay balanced and flat without constant tension adjustments.
