Spun Polyester No. 50

Where Modern Meets Tradition


Our 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.
