Magna-Glide Classic for embroidery or sewing machine or anything that takes a style L bobbin! No backlash, uniform tension, fewer bobbin changes, increased productivity, no over spin, and clean running! I have been in business for years and these are the BEST that I have found EVER!!!!
~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!
~HIGH-QUALITY YARN
Only the finest quality, high tenacity polyester yarns are used to make the patented magnetic-core embroidery bobbin.
~CLEAN RUNNING
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.
