Using these addi Turbo circular needles is easy. Just thread your yarn through the cord and start knitting as you normally would. The smooth nickel coating helps the yarn glide, so you can work faster. When using, be aware of the non - standard sizing for some smaller needles as described. After your knitting project is done, gently clean the needles with a soft cloth to keep them in good condition. Store them in a dry place, away from sharp objects that could scratch the coating or damage the cords.
