Uniform Tension Control - The patented Magna-Glide magnetic core creates consistent delivery throughout the entire Magna-Glide bobbin. No more interruptions for tension adjustments as your bobbin gets smaller. Magnetic core prevents backlash or over spin and eliminates the need for check springs.
Fewer Bobbin Changes - The Magna-Glide magnetic core bobbin offers significantly more stitches per bobbin reducing defects and increasing productivity.
Clean Running - Advanced EB cross-link technology reduces lint and residual build-up in the bobbin case and tension spring. The result is a more trouble-free Magna-Glide bobbin.
High Quality Yarn - Fil-Tec uses only the finest quality, high tenacity polyester yarns to make it patented Magna-Glide magnetic core embroidery bobbin.
