GRAV Large Gravitron Glass Gravity Bong

Our GRAV Large Gravitron Glass Gravity Bong  upgrades the classic gravity bong with a durable two-piece glass design built for flower. Heavy-duty 5mm borosilicate glass provides a substantial feel, while the closed system uses gravity and pressure to contain smoke. A platinum-cured silicone grommet protects glass contact points, and the included 19mm Funnel Bowl completes the setup.
