Spacewalk Glass Duo Carb Cap
This quartz carb cap has a dual function depending on the type of airflow you are looking for. One side has a rounded bubble edge with the airflow hole at a slight angle, while the other side is concentrated on the downward direction flow.
Carb Caps step up your dabs by trapping and circulating the heated air inside the bucket to speed up the process. The directional nozzle pushes air into the place you dropped your dab spreading it against the hot surface helping to vape it completely.
