Bernina Yellow HT Bobbin Case for B4 B5 & B7 Series

The genuine Bernina Yellow High Tension bobbin case is designed for machine embroidery and free-motion quilting where greater bobbin tension is needed than the standard black bobbin case provides. The increased tension draws the upper thread slightly more to the underside of the fabric, delivering a cleaner, more polished result on the top surface of your work.

Particularly useful when working with dense embroidery designs or free-motion quilting, the high tension bobbin case gives you greater control over thread tension without requiring adjustments to your machine settings.
