GRAV | Gravitron Glass Gravity Bong | Medium

The GRAV Medium Gravitron brings a gravity-operated design to a compact, 9-inch glass bong. Made from 5mm borosilicate glass, it features nested chambers and a silicone grommet that cushions the bottle’s contact with the base. A 14mm funnel bowl completes the setup.
