The fixed Knit RED circular knitting needles are also incredibly easy to use. The matte finish will not reflect any light, which normally makes it hard to see your work. These needles are made of stainless steel, a hypoallergenic material that is safe to use for most people with a nickel allergy. Steel alloy is very strong, wear resistant, lightweight and fully recyclable. The smooth surface ensures that the yarn glides off the needles effortlessly. With a slight bend, which reduces hand and arm fatigue, especially when there are several stitches on the needle. The transition between the needle and the RED cable is seamless. The extremely flexible (and memory-free) cable with red nylon coating consists of multiple steel wires, which prevent the cable from kinking or twisting while knitting. The needle size has been laser imprinted on each needle.
