ChiaoGoo Knit RED™ line of surgical stainless steel 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!
