Each BERNINA hook system has its own bobbin cases for
sewing, embroidery and bobbinwork. There is a bobbin to
match each bobbin case.
The 7 Series has two hooks: the B9 hook and the BERNINA
Sometimes you need more tension on the bobbin thread than usual for embroidery, free-motion sewing or free-motion quilting. And thats why you need the golden-yellow bobbin case. This high thread tension bobbin case comes standard with the B 500 and B 700.
