Ultima Style-A Class-15 Clear Plastic Sewing Machine Bobbins, 100 Pack
Description
The Ultima's Style A class 15 bobbins, also referred to as universal bobbins, are meticulously designed for sewing machines with removable and top drop-in bobbin cases. Available in transparent plastic, these bobbins are offered in packages of 10 or 100. It's important to note that they are not compatible with Bernina, Elna, Husqvarna/Viking, Janome/New Home, and Pfaff machines.
With a depth of 7/16", these bobbins are engineered with a security notch to ensure consistent thread winding. Their lightweight plastic construction provides convenience for quick sewing tasks. For optimal performance, it's recommended to use plastic bobbins with a compatible bobbin case. Consult your sewing machine's manual to determine the most suitable bobbin material for your specific model. To maintain consistent thread tension, it's advisable to stick to either metal or plastic bobbins rather than switching between the two.
