AllStitch Magnetic-Core (sideless) Pre-Wound Bobbins — Style L | White | 100-Pack | 135 yds/Bobbin

Engineered for production embroidery, AllStitch Magnetic Core (sideless) Bobbins deliver the consistent tension, clean running, and high yardage that serious embroiderers demand. Wound with industry-standard twisted polyester thread, these magnetic bobbins eliminate backlash, over-spin, and bird nesting — so you spend more time sewing and less time troubleshooting.

Designed for use with metal bobbin cases, AllStitch magnetic core bobbins maintain uniform tension from the first stitch to the last, letting you run out every yard of thread without a single tension adjustment.

Why AllStitch Magnetic Core Bobbins?

• Uniform Tension Control — The magnetic core delivers consistent thread delivery throughout the entire bobbin. No tension adjustments as the bobbin gets smaller. No check springs needed. No backlash or over-spin.
• Fewer Bobbin Changes — At 135 yards per bobbin, you get significantly more run time per change, reducing defects and maximizing production output.
• Clean Running — Advanced cross-link technology minimizes lint and residue buildup in the bobbin case and tension spring, keeping your machine running trouble-free longer.
• Premium Polyester Yarn — Wound with high-tenacity 100% continuous filament polyester for strength, smoothness, and reliable performance across all compatible embroidery machines.
