The original line of fixed RED Stainless Steel Circulars uses a flexible, multi-strand, steel cable coated with red nylon that allows your yarn to slide right over and have NO memory. Made of surgical-grade stainless steel they have a smooth, satin-sheen finish that won't reflect any light making it hard to see your work. The spectacular tips and joins are precisely machined and are lightweight and strong. The 12" (30 cm) lengths have a bend in the needle to help ease hand fatigue. Needle size is permanently laser imprinted on each circular.
