The Origins: Grenco Science
Before most consumers knew what a vape pen was, Grenco Science was building them. Founded in 2012 in Los Angeles, the company launched the G Pen brand at a time when portable vaporizers were crude, unreliable, and far from mainstream. They helped change that, becoming pioneers in both the wax pen and dry herb vaporizer categories.
The original G Pen was among the first sleek, pocket-friendly wax pens to gain widespread adoption. While the technology was primitive by today's standards, it proved that concentrates could be consumed discreetly and conveniently - a revelation that shaped the entire industry.
