Named for their thin cylindrical shape associated with pens, dab and wax pens are used to smoke oils and concentrates.
Wax pens use heat to melt the concentrations of substances, using a heating coil. They consist of a battery, a chamber with a heating coil, and a mouthpiece for inhalation. These kinds of vaporizers use a good amount of heat which is why they are protected by a steel casing which protects the smoker from burning their hands.
Dab Pens are used to smoke dabs. They work similarly to the wax pens. When the dab is placed on the heating coils, it melts it into a wick which is further absorbed and heated into a vapour which is then inhaled.
