Fil-Tec Pre-wound Bobbins

All of our pre-wound bobbins have a magnetic core.

This helps eliminate may bobbin case tension issues and backlash problems. 

We stock them in both L and M sizes for long arm quilting machines. 

Some quilters find that removing the back lash spring from the bobbins helps the magnetic bobbins run better.  

Many domestic machines can also use the L size pre-wound bobbins. 

Our 60 wt pre-wound white and black bobbins are perfect for your Embroidery Machines!
