G Pen

G Pen (formerly Grenco Science) engineers some of the most advanced, user-friendly portable vaporizers in the world. Founded in 2012, Grenco Science changed both the face and the game of the vaporizing industry.

They are known for their classic G Pro, available in a variety of styles and colors for every kind of smoker. Grenco Science has even collaborated with other artists and brands, including Snoop Dogg. If you're looking for a classic but fashionable way to vape, Grenco Science is the epitome of a brand you can trust.

Smoke Cartel's stock of Grenco Science pens is among one of our favorite product lines, and we trust that there's a Grenco Science vape for every kind of smoker.
