Ergonomic Design

The G Pen Pro could be the most ergonomic vaporizer design available. The button is in the just the right spot, and the overall design begs to be held. Aluminum outer body material makes the G Pen Pro dry herb vaporizer super lightweight and durable.


Use a small cleaning brush between every time you empty the G Pen Pro. This will help remove any residual debris from the chamber. For a deeper clean, cotton swabs and isopropyl alcohol can be used. The chamber should be fully dried before subsequent use.

  1. This vaporizer has a ceramic chamber and a much improved mouthpiece from previous models. This unit has the standard red, green and blue heat setting. But it also has a battery life indicator!! Which is a great addition. Unit heats quickly and is super easy to clean. I really enjoy using this unit.
