Kingpen oil is made in their own state-of-the-art manufacturing lab. It is distilled 5 times producing a high quality product that passes strict qualitative and quantitative tests. They then add proprietary blends of terpenes to achieve the best flavor possible. No PG, VG, PEG or other additives. 

KingPen’s hardware maintains some of the lowest failure rates in the industry and their cartridges are engineered for smooth and consistent airflow. In addition, their pens have multiple voltage levels so you can control your heat settings (low, medium and hot) and feature a pre-heat mode that allows you to heat the oil before you hit.
