Fil-Tec's M/Jumbo patented magnetic-core 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. Each bobbin has 135 yards of continuous polyester filament thread. Contains 100 per box. Available in white and black.
