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.
