Singer Plastic Class 66 Bobbins - 8pk

This set of 8 Class 66 plastic bobbins serve as replacements for many SINGER sewing machine models as well as other brands with drop-in bobbins. Consult your machine's manual to ensure correct bobbin size. Use the bobbins beneath the needle plate in automatic sewing machines to wind the thread for your embroidery projects. Never add thread to a partially wound bobbin, as it may be uneven and cause thread to tangle or break. These bobbins are not compatible with Bernina, Elna, Husqvarna/Viking, Pfaff, or Janome/New Home.
