Bamboo Interchangeable Circular NeedlesInterchangeable Circular Needles of the finest Japanese bamboo are a joy to knit with. The needles gradually get sharper, making the needles ideal for all types of yarns and projects. The cable ends are smooth so the stitches slide effortlessly over the needle without sticking at the junctions from needle to cable. The cable transitions are coated with 24 karat gold for a delicious, exclusive look. Bamboo is known to be both strong and lightweight.
