ChiaoGoo's Knit RED Circular Needles are super-smooth and super-tough! Crafted from high-quality stainless steel, the steel cable is coated with smooth red nylon making it easy for your yarn to slide across. Offered in a wide range of sizes, from US 000 to US 11, and lengths, 9 to 40, Knit RED has the perfect needle for any project. These needles have blunter tips than their sister needle, ChiaoGoo RED Lace Circular needles, but still have the same soft and smooth finish.
