Grav | Large Gravitron

The Large Gravitron® takes the gravity bong out of the dorm room. With this classic design, gravity and pressure work together to give you huge, efficient hits. But unlike homemade grav bongs fashioned from soda bottles and buckets, this sleek glass gravity bong keeps things clean and classy. Since its original 2004 release (yeah, 2004) the Gravitron has seen major upgrades. This version is made from the highest-quality borosilicate, 5x thicker than before. You'll feel it in your hand—this baby is chonky.
