Versatile Compatibility: These bobbins are compatible with a wide range of sewing machines, including select SINGER models and other top drop-in bobbin sewing machines. PLEASE CONSULT YOUR MACHINE MANUAL TO DETERMINE COMPATIBILITY.
Durable Material: Made of high-quality plastic, these bobbins are designed to withstand regular use without breaking or wearing out easily. This feature ensures that you get a reliable and long-lasting product that you can trust for all your sewing projects.
Thread Management: Using partially wound bobbins can lead to uneven thread tension, tangling, and thread breakage. It is important to use these Class 66 bobbins only when fully wound. The bobbin’s transparent design allows you to see when thread is running low, ensuring that your sewing projects remain smooth and hassle-free.
Correct Bobbin Size: Consult your sewing machine’s manual to ensure that you use the correct bobbin size. Using the wrong size may lead to damage to your sewing machine and cause thread breakage or uneven stitching. Never substitute the recommended bobbin size.
