The thick-oil glass cartridge.

The QBD-g1 glass body cartridge specializing in easy capping, quick priming, and amazing performance with high viscosity oils. It’s clog resistant by design, and boasts the first cotton free coil in an all glass cartridge.

The first cotton-free cartridge


The innovative coil of the QBD-g1, utilizes ceramic to wick oils, instead of traditional cotton. This leads to better flavor over the lifetime of the cartridge, and less of a chance of burnt coils. Due to silicone high heat conductivity, the chances of dry coils are even lower. This cartridge is also low waste, with it’s oversized gaskets to channel oil into it’s large 3x1mm intakes.

Clog resistant all glass cartridge

Finally, the QBD-g1 delivers some of the best reliability of any of the glass cartridges. The larger diameter air stem combined with a raised air inlet allows for clog resistant performance. The ceramic element (manufactured by Cerall) is the first to be utilized sans cotton, enclosed in a high temperature silicone gasket. This cartridge is designed to run flooded, and delivers walloping hits with thick materials, like Δ8. Due to the high amounts of silicone in this design, please limit terpene concentration to 6%

The simplest design

Glass body cartridges are the easiest cart on the market to fill and cap. This is due to the all glass cartridges’ unique vial style design. First, filling is as simple as shooting one’s extract against the sidewall.The operator only needs to avoid the center posts. Second, capping speed is unimportant, because there is no space for leaks in the all glass cartridge body.
