The Mix ?N? Ball Joint Adaptor has an inside coil similar to a drill bit, which the smoke passes along and cools on the way to your relieved throat.
The metal ?roach? tip goes into the end of your herbal concoction and you then insert the end of the joint into the snug fitting slot provided, and proceed to smoke your joint through the Mix N Ball J-Adaptor.
Enhances the pleasure of smoking immensely.
