The Cose N.90 Stretch Sewing Machine Needle, in a pack of 5, is compatible with most domestic sewing machines with the 130/705H system, adapting to different types of fabric depending on the thickness and shape of the point. It is important to replace the needle regularly, as wear on the point can damage the fabric, cause skipped stitches, or overload the machine mechanism. The specially rounded stretch point was developed for elastic fabrics and fine knits, preventing the needle from skipping stitches or damaging the elastic fibers during sewing.
