Based in Austin, Texas, Grav Labs entered the scene over a decade ago and have never looked back. They continuously find new ways to create scientific glass bubblers, bongs, vaporizers, steamrollers, dab rigs and pipes through their various lines of products. The “Grav Gold” pieces contain higher-end attributes for the discerning smoker. The “Helix” products have technological features that include a “venturi chamber” that causes your smoke to mix with air for smoother hits. These differing designs and styles ensure that every smoker can find the perfect glass pipe at an amazing price.
