KNITPRO Karbonz fixed circular needles come in four cable lengths and a wide range of sizes for knitting in the round on projects big or small, from sleeves to blankets. This needle is 100 cm (39.4 in) overall in 3.50 mm (US 4), a practical size for hats, shawls, and long rows where extra cord length helps. An even join is designed to help prevent snagging, and the smooth finish is meant to reduce dragging so you can keep tension steady.
