The G Pen Pro Vaporizer is an affordable portable vape enabling discreet dry herb consumption wherever life leads you. Unlike most portable vaporizers, the G Pen Pro by Grenco Science features convection heating, delivering clean-tasting, smooth, and flavor-rich vapor free of irritants. The G Pen Pro vaporizer features three presets temperature settings for the most popular strains of ground herbs. A large herb chamber, characteristic of Grenco Science vaporizers, gives you longer sessions with fewer reloads. Similar to its sister vape, the G Pen Elite, the G Pen Pro Vaporizer combines high-quality materials, advanced heating, and intuitive usability to provide a discreet and satisfying vaping experience.

  • Compatible with Dry Herbs
