134yd 144/bx POLY FILAMENT

Madeira's magnetic-sided bobbins have consistent tension through out the life of the bobbin. 

These L style bobbins are pre-wound that are magnetic-sided on one side and paper-sided on the other side. The magnetic side helps prevent back lash and provides a uniform tension. The continuous polyester filament helps reduce lint build-up in metal bobbin cases. Each bobbin has 134 yards of continuous polyester filament thread. Contains 144 per box. Available in white and black.
