To start using the Terp Pen, remove the cap and load your material. Loading the device is one of the ways the Terp Pen shows its versatility--either apply oily material to the tip with a tool, or press the heating tip directly into your material. Regardless of your loading method, care should be taken to keep the Pen's 1mm vaporpath clean to avoid clogs. Cleaning is as easy as unscrewing and disassembling the five components of the Terp Pen, and then wiping them clean with Isopropyl per the included guide.
