The Gridded Inline Bubbler Dab Rigs by Diamond Glassworks are a simple yet very effective rig for herb, oil, or wax smoking. The mini can shape water chamber features a fixed gridded inline perc to diffuse your smoke or vapor and increase airflow through the chamber, while the angled mouthpiece provides splash-proof hits. A flower bowl is included but the reinforced female joint and size of the rig make it perfect for a quartz banger or enail set up as well.
