Using these ChiaoGoo Interchangeable Adapters is easy. First, make sure you have the right - sized ChiaoGoo Twist Red Cable and ChiaoGoo Twist Lace Tip. Then, simply twist one end of the adapter onto the cable and the other end onto the tip. You can use it to connect large tips to small cables, small tips to mini cables, or even join two different - sized cables. When using, don't twist too hard to avoid damage. After use, store the adapters in a dry and clean place. If they get dirty, you can gently wipe them with a soft cloth.
