Navy Prewound Bobbin Magna Qlt M

Fil-Tec Magna-Quilt Prewound Bobbins are made from Egyptian Long Staple Mercerized Cotton No. 50 (Tex 24), combining the look of cotton with the strength and colorfastness of polyester. The magnetic core rotates the bobbin consistently throughout the entire bobbin, providing uniform tension and increasing the number of stitches per bobbin. This means fewer bobbin changes and more time quilting without fear of backlash or overspin issues. Each jar contains 10 M Jumbo style prewound bobbins, with 132 yards of thread per bobbin and 50 weight thread. Perfect for sewing, quilting, and embroidery, these bobbins are an excellent choice when quality and consistency are what you need.
