G Pen by Grenco Science


G Pen Herbal Vaporizer™ was specifically designed for use with dried herbs and comprises a stainless steel outer encasement, a hardened glass sleeve, and the tank in which dried herbs are vaporized.

However, we got sent the G Pen Vaporizer that’s designed for use with (thicker grade) oils, for which it uses a plastic tank that is filled with a syringe. There’s also a model that uses a nail and tank system.

Which is a bummer, since the G family of devices, look well built and feature attractive designs.
In short, when you’re considering which e-pen to buy you need to pay close attention to what is used and what add-on accessories are available.

The G arrives in a flip-top black box that feels quite classy.


The unit itself uses the standard G Pen battery, G Coil heating section and comes with 2 glass containers, wall and USB chargers and a dabbing tool.


As part of their new partnership, Grenco Science has also released the Snoop Dogg G Pen Herbal Vaporizer™, the first in a collection of upcoming releases designed by Snoop himself, The Double G Series.

Fully customized including a Snoop Dogg engraving, The Snoop Dogg G Pen features a decorative roadmap of Long Beach on the vaporizer and the inside perimeter of the box.

The device itself appears to be the same stainless steel outer encasement, hardened glass sleeve, and tank in which dried herbs are housed and vaporized. We looked forward to getting our hands on this one.

Grenco Science has certainly cornered the market for lovers of rap music and herb. They have big plans for 2014. We should expect to see more artist collaborations, which could mean more artists designing their own pens.
