Gpen

G Pen, associated with the brand name Grenco Science, designs and sells portable vaporization hardware for dry herb and concentrate materials. Its catalog spans handheld dry herb vaporizers such as the Dash II ($49.95) and Dash+ ($99.95), concentrate devices including the Micro+, Connect, Hyer and the Roam portable e-rig, the Melt hot knife for handling concentrates, a line of 510-thread cartridge batteries (G Pen 510 Original and Hydout, priced $12.95-$24.95), and accessories such as a three-piece slim aluminum grinder with micro-rounded teeth and a screenless design.

The company states its devices use conduction and convection heating methods, and it positions its dry herb devices around flavor and vapor smoothness and its concentrate devices around compact form factors. Alongside its own product lines, G Pen sells co-branded collaboration editions of existing devices with consumer and cannabis-adjacent brands including Cookies, Lemonnade, Dr. Greenthumb's and Grateful Dead. The site also merchandises a THCa category and publishes educational content, including a vaporizer buying guide and a blog with how-to and cleaning guides, supported by a customer service team handling troubleshooting, shipment tracking and account inquiries.
