About Us

G Pen has been making portable vaporizers since 2012. We design devices that are simple to use, easy to carry and built to last, for dry herb, for concentrates and for 510 cartridges. G Pen is made by Grenco Science (GS Holistic LLC).

What we make

• Dry herb vaporizers: the pocket-sized Dash II and the Dash+.
• Concentrate vaporizers: the Micro II, our smallest portable dab rig, the Roam portable e-rig and the Connect, which works with the glass you already own.
• 510 batteries: the 510 Original and the Hydout, for standard 510 thread cartridges.
• Tools and accessories: the Melt hot knife, our 3-Piece Slim Grinder, and replacement tanks, mouthpieces, screens and batteries for every current device.

Collaborations

Over the years we have teamed up with artists, musicians and brands, from the Snoop Dogg G Pen to editions with Cookies, Lemonnade, Dr. Greenthumb’s and the Grateful Dead. See what is available now in our Collaborations collection.
