Our RED Lace Stainless Steel Circulars are made of surgical-grade stainless steel with a smooth, satin-sheen finish. The cable is made of flexible, multi-strand, steel coated with red nylon that allows your yarn to slide right over and has NO memory.  The spectacular tips and joins are precisely machined and are lightweight and strong.  Needle size is permanently laser imprinted on each circular. They are user-friendly to knitters who are sensitive to nickel.
