Pre-wound Bobbins

                                                Pre-Wound Bobbins by Fil-Tec

*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!
