The G-Pen Connect Concentrate Vaporizer from Grenco Science is made to work with glass-on-glass water pipes and eliminates the need for a torch and a nail. The ceramic plate heating element provides superior flavor and vapor production from the user's concentrates while the spring-loaded carb release makes it easy to clear vapor from the glass rig without having to pull off the entire vape unit. The powerful 850mAh battery provides manual and automatic heat-up and provides three variable voltage heat settings. The battery and tank cap have magnetic connections for easy placement and removal.
