The FOGG dry herb atomizer is the heating element that heats up The Fogg Pen™ and turns herb into a vapor. One end snaps snuggly into the battery and the other end fits the mouth piece. It consists of a small pot or chamber, which holds a reserve of the oil. There is a metal coil/wire, which draws in the liquid from the cartridge to a wick. The heating element heats up the herb and turns it into a vapor, which is then drawn back through vent in the mouthpiece by the user. The atomizer is often the source of issues with performance and taste.
** You MUST break in/season the atomizer with herb before first use, to achieve the full flavor and taste.
