How do I properly draw from my G Pen Gio?

The G Pen Gio is breath-activated, so once the unit is charged and has a cartridge inserted, you’ll only need to draw through the unit’s mouthpiece until the desired amount of vapor is consumed.

If you have any further inquiries, please contact our Customer Service Department anytime Monday through Friday, 8:00am to 5:00pm PST.
