Magna-Glide Classics are produced using 60wt. filament polyester thread on a patented magnetic-core that creates consistent delivery throughout the entire bobbin. No more interruptions for tension adjustments as your bobbin gets smaller. Magnetic-core prevents backlash or over spin & eliminates the need for backlash springs.
M Style - Bag of 10 Bobbins. 210-230 yards per bobbin depending on color.
