Ultima Style-A Class-15 Clear Plastic Sewing Machine Bobbins, 10 Pack
Description
Ultima's style A class 15 bobbins, commonly known as universal bobbins, are specially crafted for machines featuring removable and top drop-in bobbin cases. These transparent plastic bobbins come in a packages of 10 and 100. They are not compatible with Bernina, Elna, Husqvarna/Viking, Janome/New Home, and Pfaff machines.
Measuring 7/16" in depth, these bobbins are equipped with a security notch, ensuring consistent thread winding. Their lightweight plastic construction offers convenience for swift sewing tasks. For optimal performance, pair plastic bobbins with a bobbin case designed for such material. Refer to your sewing machine's manual to determine the ideal bobbin material for your specific model. To maintain uniform thread tension, it's advisable to stick to either metal or plastic bobbins rather than switching between the two.
