G Pen (Dual Quartz Coil)

Grenco Science

G Pen with Dual Quartz Coil for Waxy Oil - Grenco Science


Packing twice the power, the upgraded G Pen Vaporizer from Grenco Science features a dual quartz rod atomizer. The discreet vape pen design of the G Pen is ideal for vaping outdoors or travel. The G Pen's powerful Dual Quartz atomizer turns waxy oil into impressive clouds of vapor. By the same token, the inert nature of the G Pen quartz coils provides the user only the natural flavors of wax concentrates with no added taste. The G Pen Dual Quartz Vaporizer from Grenco Science is the ideal companion for waxy oil enthusiasts who need a stealthy way to vape on-the-fly.


The G Pen should be cleaned on a regular basis in order to maximize functionality. We recommend using a clear alcohol solution to clean the screw threads in the G Pen atomizer; this ensures consistent electricity runs to the device. Let your G Pen Tank dry before re-attaching for use. Make sure you let your battery charge completely before use in order to maximize the life of the G Pen battery.

Wipe down the exterior of the G Pen Dual Quartz Vaporizer with a damp cloth to remove excess oils and everyday dirt and grime. The mouthpiece can be detached from the G Pen and washed gently with warm water and dish soap to keep your G Pen sanitary. Careful care and maintenance can greatly expand the longevity of your G Pen Dual Quartz Vaporizer.

Considered a healthier alternative to traditional methods of smoking. Vaporizers do just what the name suggests; they create vapor rather than combustion of your smoking material. Vaporizers can be used for dry herbs ,concentrates or essential oils (depending on the style of vaporizer you purchase). Vaporizers are available in many styles, including tabletop vaporizers, vape pens and other portable designs. As mentioned, be sure to purchase a vaporizer that is suitable for the material you will be smoking i.e. flower, concentrate or oil. CLICK HERE to see our full selection of vaporizers.
