Singer Class 66 Clear Bobbins - 16 PK

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