Magna-Glide Classic vs Paper Sided bobbins

This is a test that shows the draw off tension of Fil-Tec Magna-Glide Classic pre-wound embroidery bobbins compared to paper sided bobbins. Both bobbins tested are style L white.
Magna-Glide Classic's patented magnetic-core creates consistent delivery throughout the entire bobbin and offers significantly more stitches per bobbin, reducing defects and increasing productivity.
