These vibrant rainbow coloured fixed circular needles are made of a strong, polished, smooth laminated birch wood. Yarn slides freely along the needle without catching, but has enough grip to easily manage slippery yarns. The 32″ needle tips are 51⁄8 inches long. Since the cable is super flexible, the Magic Loop method of sock knitting can be accomplished with the 32″ needles for one sock at a time.
