Threaded Bobbins, Transparent, Black & White, 12-Count

This set of 12 Class 66 threaded bobbins is suitable for use in SINGER and other manufacturers' top drop-in bobbin machines. The pack comprises 6 black-threaded bobbins and 6 white-threaded bobbins, each containing 50 yards of 100% spun polyester thread. The reels are housed in a reusable plastic case, ensuring convenient storage and accessibility.

When using these bobbins, it is crucial to consult your machine's manual to confirm the correct bobbin size. This step is essential to ensure optimal performance and compatibility with your sewing machine. Failure to use the appropriate bobbin size may result in uneven thread tension or thread breakage, which can disrupt your sewing project.

One important consideration when using these bobbins is to never add additional thread to a partially wound bobbin. This practice can lead to uneven winding, potentially causing the thread to tangle or break during use. To maintain the integrity of the thread and ensure smooth sewing, it is recommended to use the bobbins until they are fully depleted before replacing them with a fresh set.

The inclusion of a reusable plastic storage case enhances the overall convenience and organization of this bobbin set. This case not only protects the bobbins from dust and damage but also allows for easy access and identification when needed. The durable construction of the case ensures that it can withstand repeated use, making it a practical and long-lasting accessory for your sewing needs.

In summary, this set of 12 Class 66 threaded bobbins, comprising 6 black and 6 white bobbins, is an invaluable addition to any sewing enthusiast's toolkit. With each bobbin containing 50 yards of 100% spun polyester thread, this set provides ample material to tackle a wide range of sewing projects. The reusable plastic case further enhances the overall convenience and organization of this product, making it a versatile and reliable choice for SINGER and other top drop-in bobbin machine users.
