The Large Gravitron from GRAV reimagines the gravity bong, transforming it from a DIY classic into a premium experience, thanks to its robust 5mm borosilicate glass, which allows for smooth hits using gravity and pressure, with no pulling required. The Large Gravitron comes with a GRAV 19mm funnel bowl, compatible with any standard 19mm male bowl for customizable setups. Just like the Medium Gravitron, the Large Gravitron’s sealed system traps smoke until you’re ready, maximizing efficiency and conserving your herb for when you’re ready for the thick vapor clouds. Standing solid, this powerhouse delivers unmatched durability and performance for enthusiasts who demand deep, clean, and effortless hits.
