Prewound Bobbin 20pc Black

This set of 20 prewound Fil-Tec Magna-Glide Delights Bobbins are the perfect addition to any sewing, quilting, or embroidery project. They are designed with a magnetic core that rotates the bobbin consistently throughout the entire bobbin, ensuring uniform tension all the way to the last stitch. This not only provides consistent tension, but also increases the number of stitches per bobbin, allowing more time for quilting and fewer bobbin changes. With 72 yards of 40 weight trilobal polyester thread on each original magnetic core bobbin, and no issues with backlash or overspin, these Fil-Tec Magna-Glide Delights are sure to help streamline your next project.
