Every knitting toolkit should hold a sturdy yarn needle or two. Features a large eye to fit most yarns and a blunt tip so you don't split the yarn (and prick your fingers).
Made from stainless steel and comes to you as a pair (the price shown is for two yarn needles). Pictured here with 12 ply yarn. Measures 5.8 cm long and is 3 mm wide at the eye.
