Features & Benefits:

• Magnetic Core = uniform tension
• Bobbin will sew to the very end without tension variation
• High yield fiber = more stitches per bobbin
• Lower cost per yard based on usable yards per bobbin

Fil-Tec's revolutionary magnetic core embroidery bobbin is the only prewound embroidery bobbin specifically designed to sew without tension variation throughout the entire bobbin. The magnetic core, combined with our advanced EB "crosslink" technology optimizes dynamic thread delivery to create consistent tension from beginning to end of each bobbin.

Uniform Tension Control
Our 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 and eliminates the need for backlash springs.

Fewer Prewound Bobbin Changes
Our magnetic core bobbin offers significantly more stitches per embroidery bobbin reducing defects and increasing embroidery machine 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 side less prewound embroidery bobbin.

High Quality Yarn
Fil-Tec uses only the finest quality, high tenacity polyester yarns to make it patented magnetic core embroidery bobbin.
