KNITPRO Karbonz fixed circular needles are suited to hats, cowls, necklines, and other projects worked in the round or back-and-forth on a short cable. This needle is 40 cm (16 in) long in a 3¼ mm size, built with a carbon-fiber body and carefully formed tips to support clean stitches at fine gauges. Its balanced stiffness and flex can help you maintain consistent stitches when shaping, decreasing, or working dense fabrics.
