The Grav Large Hammer Bubbler is a compact 4” inch tall, 7” inch long glass pipe that delivers the smooth hits you’d expect from a water pipe in a palm-sized, hammer bubbler design. Made from high grade borosilicate glass with 32mm diameter tubing, this clear glass Grav Hammer contains a highly thermal-resistant airpath that preserves the true flavors of your dry herbs in smooth moisture-conditioned rips. The Grav Hammer Bubbler is equipped with a fixed flower bowl that leads into a cross-cut downstem, with clear marble feet that act as a roll-stop allowing you to table your new hand pipe in between use without spilling the contents. We recommend filling the base with approximately 0.5” inches of water for optimal filtration. A sleek and portable bubbler pipe for the sophisticated smoker, the Grav Hammer Bubbler is affordably priced and a clutch pickup for any smokers glass collection.
