These ChiaoGoo double-pointed needles are made with stainless steel (RVS), a very strong and wear-resistant material that is lightweight and fully recyclable. The tapered tips make it easy to knit your stitches and the smooth surface ensures that the yarn glides off the needles effortlessly. Ideal for circular knitting projects with few stitches, such as socks, stockings or gloves. These double-pointed needles are very user friendly. The matte finish will not reflect any light, which normally makes it hard to see your work. Further, RVS is hypoallergenic, therefore safe to use for most people with nickel allergies as well. The needle size has been laser imprinted on each needle. The double-pointed needles by ChiaoGoo are available in 15 and 20cm lengths and in several needle sizes. Supplied per 1 set of 5 double-pointed needles.
