These fixed circular knitting needles by ChiaoGoo are made of stainless steel attached to a pliable nylon cord. Ergonomonically designed, the slight curve at the join allows for a comfortable knitting experience. Each needle is stamped with the brand and needle size on it for easy organisation. For best results, it is suggested that you relax the cables in boiled water prior to using them for the first time. These needles have been discontinued by the manufacturer. As such, they are on clearance and are available while supplies last.
