Measuring a travel-friendly 3” inches tall by 5” inches in length, the Grav Mini Hammer Bubbler was designed to always get the job done whether you’re at home or on-the-go. This portable glass bubbler pipe features everything you need for smoother hits from your dry herbs including an X-cut diffuser downstem that filters your smoke through water within the base of the main chamber. A fixed flower bowl on the top leads your smoke through the fixed downstem, while a left side air carb hole offers complete control over the size of each hit. We recommend filling the base with approximately ½” an inch of water for optimal filtration and draw resistance.

Two worked glass marbles act as stabilizing feet to keep this hammer bubbler standing upright between uses, while the lack of removable parts ensures your glass always stays say when on the move. The Grav Mini Hammer Bubbler is made from clear borosilicate glass on 25mm heavy wall tubing, and finished with a sandblasted GRAV decal on the front. Practical, elegant, and highly affordable, the Grav Mini Hammer Bubbler will make a great addition to anyone’s glass collection.
