Quick answerG Pen is a vaporizer brand from Grenco Science. Its lineup covers three jobs: dry herb vaporizers (Dash, Elite II), concentrate devices (Micro+, Roam, Connect) and 510 cart batteries (510 Original, Hydout).

What is G Pen?

G Pen started as one of the first pocket vapes and grew into a full lineup — plus a long list of collaborations with brands like Cookies and Lemonnade. The trick to buying one is simple: match the device to what you put in it.

A small story about spare parts

Every G Pen owner has the same moment: the device still works perfectly, but the mouthpiece cracked or the tank wore out. Most people buy a whole new device. You don’t have to — mouthpieces, tanks, glass adapters and batteries are sold separately, and swapping one takes a minute.
