Please consult your machine’s manual to determine compatibility. In machine sewing, the bobbin thread forms the bottom part of your stitches, working with the top spool thread for strong, consistent stitches. Made from high-quality plastic, these bobbins ensure smooth thread winding and unwinding, preventing stitch irregularities and machine jamming. Using SINGER Bobbins is simple: wind your thread onto an empty bobbin, ensuring it is correctly seated in the bobbin winding tension disk of your machine. For best results, use bobbins that match the class/style of those that come with your machine and wind thread onto empty bobbins only, ensuring proper tension. Replace any bobbins that become chipped, bent, or damaged. Whether you're creating clothing, quilts, or DIY home décor, the pack of 4 SINGER Class 66 Transparent Bobbins delivers professional results with ease.

The transparency of these bobbins is a game-changer. Being able to see the remaining thread supply at a glance saves me time and frustration, ensuring I never run out of thread unexpectedly mid-project. It's a simple yet ingenious feature that enhances the overall sewing experience.In terms of performance, these bobbins excel. Crafted by a trusted brand like SINGER, they boast exceptional quality and durability. I've found that they wind smoothly and evenly, resulting in consistent tension and stitch formation. Whether I'm working on delicate fabrics or heavy-duty projects, these bobbins deliver reliable results every time.The pack of four bobbins is also a great value proposition. It provides an ample supply to keep my sewing without interruption, and the convenient storage case ensures they stay organized and easily accessible.

I thought sure being Singer branded metal 66 bobbins these would work great on my Vintage 1956 Singer 99k which takes class 66 bobbins. I can run them in my machine and they fit perfectly into the bobbin case but unfortunately the smallest hole does not line up to the pin on my bobbin winder, it is just 1-2 mm off, so I can't wind them on this machine. I don't know if I got a bad pack or if they are all made this way, but I will be returning these and looking for a different brand or looking for some vintage ones that I know will work.

I think they aren't quite as good as my 30 year old Bobbins but they are good and get the job done. Good price and better than the generics I returned that were aweful. These are good and fit right in the machine.
