~UNIFORM TENSION CONTROL
The patented magnetic-core 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.
~FEWER BOBBIN CHANGES
Magnetic-core bobbins offer significantly more stitches per bobbin, reducing defects and increasing productivity. White is 135 yards!
Only the finest quality, high tenacity polyester yarns are used to make the patented magnetic-core embroidery bobbin.
Cross-link technology reduces lint and residual build-up in the bobbin case and tension spring. The result is a more trouble-free bobbin.
*Remember to remove the anti-backlash spring from the metal bobbin case prior to use.
**Always insert the magnet down into the metal case.
