Singer Plastic Class 66 Bobbins - 4 count

The SINGER Transparent Plastic Class 66 Bobbins serve as replacements for many SINGER sewing machine models as well as other brands with drop-in bobbins. Consult your machines 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.
