GRAV Medium Gravitron Glass Gravity Bong

Our GRAV Medium Gravitron Glass Gravity Bong brings GRAV’s signature gravity-powered design to a compact two-piece glass setup. Built from heavy-duty 5mm borosilicate glass, it uses a closed system to contain smoke and features a platinum-cured silicone grommet at the glass contact point. The 14mm female joint and included GRAV Funnel Bowl make it ready for flower.
