The polished wood surface of Knitter's Pride's bamboo knitting needles works effortlessly with every type of yarn without slowing down stitch rhythm. With a cuboid shape with square cross-section, round point and light weight, the Cubics tips offer hours of knitting pleasure. Each needle tip is imprinted with the needle size for ease of use. Cubics Special IC tips have a shorter (3") shaft that can be used with 16" cables to a 16" circular needle from tip to tip.
