Fil-Tec Magna-Soft Style M Magnetic Core Prewound Bobbins 50wt 10pc Jar

Magna-Soft bobbins are made from high-quality polyester yarn, and are designed for intricate quilting and piecing applications. Magna-Soft bobbins provide substantially more stitches per bobbin along with uniform tension throughout the entire bobbin.

Main Features

Consistency
Fil-Tec’s patented magnetic-core creates consistent delivery throughout the entire bobbin. No more interruptions for tension adjustments as your bobbin gets smaller. Magnetic-core prevents backlash or over spin & eliminates the need for backlash springs

Perfect Match
Magna-Soft pre-wounds are a perfect match to their corresponding Premo-Soft color, giving you a perfect match on the bottom & top of every piece you stitch.

High Quality Yarn
Fil-Tec uses the highest quality polyester yarns to produce Premo-Soft & Magna-Soft.

Clean Running
Advanced EB cross-link technology reduces lint & residual build-up in the bobbin case & tension spring. The result is a more trouble-free bobbin.
