Fewer Bobbin Changes
The magnetic-core bobbin offers significantly more stitches per bobbin, reducing defects & increasing productivity.

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

Clean Running
