Towa Pigtail Bobbin case M size

Towa Jumbo M Bobbin Case with pigtail and stainless steel anti-backlash spring.

Fits A1 and Handi Quilter machines (does not fit a Gammill sorry)

The pigtail guide provides slightly more tension on the bobbin thread PLUS guides it perfectly and consistently directly up through the hole in your throat plate. Less movement of the thread and minimises it whipping in the hook area.
