A Bobbin Case is required for machine embroidery, and holds the bobbin in the machine. It is locked into the hook by a latch on the case. Our M bobbin cases are offered with and without a backlash spring. Try our fine premium bobbin case and we believe you will stay with them forever. (Fits all commercial machines that feature a "Jumbo" rotary hook).
