White L Style Plastic Sided Bobbins

These bobbins are made using high strength, high tenacity poyester 70D/2 thread. Don't be fooled by cheap prewound bobbins that use lower quality regular tenacity thread when comparing brands. There is a difference. High tenacity thread resists breaking and run great at high stitch speeds. Spend more time embroidering instead of correcting thread breaks. 120 yards of 70D/2 high tenacity filament polyester thread each. L style for Viking, Pfaff, Brother, Bernina, Elna and Babylock. 144 per box
