G PEN SHIPS BY THE CASE

Grenco Science puts almost everything it makes under one sub brand, G Pen, then splits the line by material. Cartridges go on the Original and the Hydout. Flower goes in the Dash Plus. Concentrate goes into the Connect, the Roam or the Hyer. Buy by material and the section plans itself.

Case pack is the second axis, and it changes the order math more than the spec sheet does. The 510 batteries and the Melt hot knife ship only in multipacks, ten or twenty to a box, which drops per unit cost well below a single. The vaporizers ship one at a time. So the batteries are your volume line and the devices are your ticket line, and they are not competing for the same customer.

  • G Pen Original 510 400mAh, auto draw plus button control, three voltages at 3.2V, 3.6V and 3.8V, 10 second preheat, digital screen and USB-C pass through charging. Twenty to a box.
  • G Pen Hydout 510 400mAh in a hard shell that swallows a cartridge up to 2G, five voltages from 2.4V to 3.8V, 10 second preheat, bright LED screen. Ten to a box.
  • G Pen Dash Plus Hybrid convection and conduction in a full titanium chamber, 20 second heat up, 1800mAh, USB-C, color display and haptic feedback in a zinc alloy body.
  • G Pen Connect 850mAh, ceramic element, patented reverse airflow, three temperatures, magnetic snap in housing and 10mm, 14mm and 18mm glass adapters.
  • G Pen Roam 1300mAh, quartz tank, self contained borosilicate hydrotube, 600F to 800F, spill proof aluminum shell, pass through charging.
  • G Pen Hyer 6,000mAh portable e-nail that takes concentrate or flower, quartz chamber, three button control and a 14mm male glass adapter.

Tanks and mouthpieces are the reorder line and they are cheap to hold. Connect owners replace the ceramic tank. Roam owners lose the silicone mouthpiece. Micro Plus owners need the tank with the quartz liner. The Connect glass adapters need the metal connector to seal, and that connector is a two dollar part that stops a hundred dollar device from working.

Cost per unit is the argument here. A twenty pack of G Pen Original batteries lands each battery in the mid single digits, which is aggressive for a variable voltage battery with a screen and pass through charging. At the other end, the Hyer runs to a hundred and fifty. That spread is why G Pen tends to occupy a whole section rather than a single facing.

Frequently Asked Questions

What are G Pens?

G Pen is the product line from Grenco Science. It covers 510 thread batteries, dry herb vaporizers, concentrate vaporizers and a hot knife. When a customer asks for a G Pen they usually mean either the Original 510 battery or a Dash, so it helps to have both facings.

Do G Pen 510 batteries come in bulk packs?

Yes, and that is the only way they ship. The G Pen Original comes twenty to a box and the Hydout comes ten to a box. Buying at the case level is what brings per unit cost down to the point where a battery can sit at an impulse price on the counter.

What is the difference between the G Pen Original and the Hydout?

Concealment and voltage steps. The Original is a compact 400mAh battery with three voltages and a digital screen, roughly the size of a tank. The Hydout is also 400mAh but wraps a hard shell around cartridges up to 2G and offers five voltage steps from 2.4V to 3.8V.

Which G Pen takes flower?

The Dash Plus. It runs hybrid convection and conduction through a full titanium chamber, heats in about 20 seconds, and carries an 1800mAh cell with USB-C charging and a color display. It is the current flower unit in the line and the one to stock if you only stock one.

Can the G Pen Connect attach to a water pipe?

Yes. The Connect is designed for glass on glass use and ships with a 14mm male adapter, with 10mm and 18mm adapters also available. It snaps into its housing magnetically and has a spring loaded carb release to clear the chamber. That pairing makes it an easy add on next to your glass.

What is the G Pen Hyer used for?

It is a portable e-nail that handles concentrate or flower and pairs with glass on glass water pieces. A 6,000mAh cell, quartz chamber and three button interface put it at the top of the G Pen range. It sells to the customer who already owns a rig and wants to stop using a torch.

Which G Pen parts sell as replacements?

The Connect replacement tank, the Roam silicone mouthpiece, the Micro Plus tank and the Connect metal connector for glass adapters. All four are low cost, all four are things customers break or misplace, and holding them turns a one time device sale into a returning customer.

Is Grenco Science the same brand as G Pen?

Grenco Science is the company and G Pen is the product line it sells under. Signage and search traffic both skew heavily toward G Pen, so label the section that way even though the invoices and the brand page say Grenco Science.

Do I need a wholesale account to see G Pen pricing?

Yes. Case pricing on the multipacks is only visible once a wholesale account is approved, which requires the licensing documents your state asks for. Approval is a one time step and it unlocks pricing across the full catalog rather than brand by brand.
