The 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 2 mm through 3 mm have the same awesome cable as our RED circulars and TWIST cables! Needle size is permanently laser imprinted on each circular.
