Made of stainless steel, ChiaoGoo Swivel Adapters allow any of the Small or Large TWIST interchangeable red or blue cables to swivel - without sacrificing the signature smoothness of the joins. Yes, even the much‑loved memory‑free red cables can now rotate freely. They’re an easy upgrade for any current ChiaoGoo interchangeable set. For Blue Shorties users, adding a swivel adapter to just one side can noticeably increase knitting comfort while still maintaining the small circumference needed for tight‑radius projects.
