About G Pen

Founded by Chris Folkerts in 2012, Grenco Science (the company behind G Pen) engineers the most advanced, user-friendly portable vaporizers on the market. In fact, Grenco Science was the first vaporizer brand to market a tank system that was designed specifically for e-liquids and aromatherapy oils. G Pen vaporizers integrate superior functionality with the convenience of transportability, and are known for pushing the envelope with their innovation. 

Since its inception, Grenco Science has strategically partnered with and acquired like-minded companies in the cannabis space, including its highly publicized April 2020 acquisition of Stündenglass Inc., engineers of the world’s first gravity powered contactless water pipe. Through the acquisition, Grenco Science has solidified their leadership position in the cannabis industry with one of the largest product offerings of vaporizers and accessories.

Ubiquitous in hip-hop culture, Grenco Science has partnered with big names in the space through its Artist Series -- a series of collaborations with industry-leading artists and brand ambassadors, including Snoop Dogg and Dr. Greenthumb’s Dispensaries. Through proprietary research and development, as well as collaborations with influencers in music, art, and fashion, Grenco Science is transforming the vaporization experience.
