Madeira Mag Core Bobbin L 308-507 White

Madeira Sideless Magnetic Core pre-wound machine embroidery bobbins are set to become a favorite in embroidery shops.

These magnetized, L-style bobbins are both strong and economical. Each bobbin is wound with 148 yards of continuous polyester filament thread, effectively reducing lint buildup in the bobbin case. The magnetic core secures the bobbin in the metal case, ensuring consistent tension throughout its use. With these bobbins, you’ll experience less over-spin, friction, and wear on the bobbin case. If your bobbin case has an anti-backlash spring, be sure to remove it before use. Each box contains 144 bobbins, available in white.
