About These Bobbins

This bulk pack of 100 Class 66 metal bobbins is specifically designed for Singer sewing machines that use the Class 66 bobbin system. These are authentic Class 66 bobbins manufactured to the correct specifications for vintage Singer machines - not the generic bobbins sold at big box stores that may not fit properly or perform reliably.

The 100-pack format provides exceptional value for serious sewers, quilters, professionals, repair shops, or anyone who wants to stock up on quality bobbins. At just $0.50 per bobbin, you can pre-wind multiple colors and always have the right thread ready to go.

Why These Bobbins Are Different

Authentic Class 66 Specifications:

These bobbins are manufactured to the exact dimensions required for Singer Class 66 machines. Many bobbins sold at retail stores are generic "one size fits all" bobbins that don't match the precise specifications of vintage Singer machines, leading to tension problems, jamming, and poor stitch quality.

Not Big Box Store Bobbins:

Please note that these bobbins are NOT the same as those sold at big box stores and other platforms. They are specifically designed for older vintage Singer Class 66 sewing machines and manufactured to the correct tolerances for proper fit and function.

Metal Construction:

Metal bobbins are superior to plastic alternatives for vintage machines. They maintain consistent shape and weight, provide better thread tension, won't warp or crack, and last for decades of use.
