Twist cables are accessories for ChiaoGoo's interchangeable knitting needle systems. These cables work equally well with the "Spin" bamboo tips or the "Twist" stainless tips. Twist cables are made of ChiaoGoo's signature red-coated steel cable. These cables do not kink, and they have virtually no memory. Be sure to purchase the correct size cable. Mini cables are for use with needle tips size US 000 (1.5mm) through US 1.5 (2.5mm), small cables are for use with needle tips size US 2 (2.75mm) through US 8 (5mm), and large cables are for use with needle tips size US 9 (5.5mm) through US 15 (10mm). Cable length is from connector to connector, so add either eight inches if using the four inch tips or ten inches if using the five inch tips to determine total needle length. Please note that eight inch cables are only compatible with the shorter, four inch needle tips.
