What Can I Get at G Pen?

New users should check out the Gio. In a JUUL-like fashion, you use a pre-filled cartridge or pod on top of a matching 180mAh battery. We really like that the battery offers pass-through charging and the entire system is breath activated. It's a fool-proof way to try a vape pen.

Periodically, G Pen works with celebrities like Snoop Dogg to create collaborative limited-edition versions of their products. If one catches your eye, don't wait too long to order. The popular ones cost a little more, but they go fast.

If you'd like to save on either a limited edition or standard model, use one of the G Pen discount codes from this page. We'll always have the latest offers.

You can also purchase charging docks, water-pipe attachments, replacement parts and other accessories from their site as well as branded shirts, snapback hats and pins.

What Do Their Customers Say?

You'll find the best feedback from customers right on the G Pen site. Short, one-line reviews from publications like TechCrunch, BuzzFeed and Medical Jane scroll across the bottom of the home page and every product page allows customers to add ratings and comments.
The reviews are a little more mixed on other sites like this Leafly page dedicated to the G Pro Vaporizer and you can find several unboxing and personal commentary videos on YouTube if you want an up-close look at the G-Pen line.

Other Information

Shipping – Standard USPS shipping is free to US customers who spend at least $75 on the site. Expedited shipping is also available for an additional fee. Shipping to other countries is limited.

Payment Methods – Credit and debit cards are accepted. If money is tight, you can spread out the cost of your new vape across 4 monthly, interest-free payments by using Sezzle.

Warranty - Most G Pen vapes include a 1-year warranty, but you must register your product to make sure it's covered. Be sure to keep your proof of purchase just in case.

Return Policy – All items except hats and clothing can be returned within 7 days of receipt for either store credit or exchange. There are no refunds so think carefully before you order.
