ChiaoGoo Knit RED have a bend in the needle to help ease hand fatigue. They are made of surgical stainless steel and circulars have a smooth, satin-sheen finish and memory-free, multi-strand, steel cable coated with red nylon allowing yarn to slide right over. The precisely machined tips are ergonomically designed with a bend to ease hand fatigue. Needle size is permanently laser imprinted on each circular. The joins are just spectacular!
