Bobbin Case Red 7 Series Machines
Bernina 9 Red Bobbin Case for 7 series models. This bobbin case is used for sewing with thicker threads, such as cordonnet threads that cannot fit through the eye of a needle.
The Bernina Red Bobbin Case is designed for reverse bobbin work. It has a very loose tension spring to allow a larger thread to slide through the bobbin case.
This bobbin case is designed to fit the Bernina 735, 740, 770QE, 770QE E, 790 and 790 Plus models.
