calculated at checkout.
This is a pre-wound bobbin filled with 90 weight polyester thread.
The clear plastic sided bobbin works in conjunction with the thread sensors , and consistently lets the operator know when the bobbin thread is about to run out. The bobbins run virtually lint-free and offer the operator significantly more stitches per bobbin than machine-wound bobbins. It also helps balance needle thread tension, and offers high tensile strength, low elongation, and low shrinkage.
