From Glass to Vape
The Grenco Science G Pen Connect turns any water piece with a glass-to-glass connection into a powerful e-rig. This palm-sized innovation is engineered with patented reverse airflow technology and a spring-loaded carb release button. The ceramic heating element evenly heats solid concentrate to deliver pure, flavorful vapor. The magnetic 850mAh battery is equipped with three temperature settings (blue: 3.1 volts, green: 3.6 volts, and red: 4.1 volts).
