ChiaoGoo's 32″ (80 cm) patina, bamboo circulars have fantastic joins and pliable, clear, nylon cables. They have a nickel-plated, copper join. Sizes 3 (3.25 mm) and larger are crimped to guarantee no separation AND they swivel! Sizes 0 (2 mm) through 2.5 (3 mm) have the same awesome cable as our RED circulars and TWIST cables! Needle size is permanently laser imprinted on each circular. Bamboo circulars are available in the patina color only.
