148 yd 144/bx POLY FILAMNT
Madeira Sideless Magnetic Core pre-wound machine embroidery bobbins are sure to be the new favorite in embroidery shops.
These magnetized, L-style bobbins are strong and economical. Each bobbin is wound with 148 yards of continuous polyester filament thread, which helps reduce lint build-up in the bobbin case. The magnetic core holds the bobbin securely in the metal bobbin case, maintaining continuous tension throughout the life of the bobbin. There is less over-spin, less friction and less wear and tear on the bobbin case with these bobbins. If your bobbin case has an anti-backlash spring, remove it before running. Each box contains 144 bobbins. Available in white.
