When screwing in your tips, connectors or stoppers, insert this tightening key(s) into the lifeline hole found on each metal join at the ends of your TWIST™ & SPIN™ cables, connectors or stoppers. Simply use the key as a handle to help you grasp and tighten the screw connection. Use the key EVERY time you attach your tips to a cable. You will need the key to loosen the connection when removing the tips from the cable.
This key fits with Chiao Goo Mini interchangeable needles and cables.
