These Tunisian Circulars are available in four different lengths ranging from 16" (40 cm) to 40" (100 cm) and are made just like the ChiaoGoo fixed bamboo circulars. They have fantastic joins and pliable, clear, nylon cables with a nickel-plated, copper join that is glued and crimped to guarantee no seperation. Both hooks swivel freely on the cable. Needle size is permanently laser imprinted on each circular. Available in patina color only.
