From ChiaoGoo: Bamboo Circular Knitting Needles 12", size 2. The needles are made from Moso Bamboo, one of the strongest and largest bamboo species in the world. Circulars feature a silver ferrel and clear, flexible cable. The cable itself spins within the ferrel so the cables do not twist as you knit. The connection between cable and ferrel is ultra smooth. This package contains one 12in set in size 2.
