Magna-Soft is a pre-wound bobbin from Hab+Dash with Premo-Soft, a 50 weight polyester thread, wrapped around a patented magnetic-core. This creates consistent delivery throughout the entire bobbin. No more interruptions for tension adjustments as your bobbin gets smaller. The magnetic-core prevents backlash or over spin and eliminates the need for backlash springs.
Magna-Soft bobbins are produced using the Premo-Soft top thread colors, giving you a perfect match on the bottom and top of every piece you stitch. Premo-Soft is a 50 weight polyester thread with a matte finish and the look of cotton.
