The Arizer replacement balloon pack is designed for the Extreme Q Vaporizer, the pack includes 6 food grade balloons or bags. The benefit of the balloon bags is the freedom of movement since the user can bring the material to vape without the need to bring the desktop unit. You can also use and re-use the bags several times, up until you notice a drop off in vapour quality. The glass mouthpiece and the O-rings are not included in this set.
