Experience the perfect blend of functionality and style with this cup dab rig, where worries about splashback are eliminated by the sharp bend in the mouthpiece, keeping all water inside the rig. Complete with a 14mm female-jointed domeless nail made of heat-tolerant quartz, this rig ensures you can dive right into the fun with just 0.5" of water. Elevate your smoking sessions with the GRAV Large Circuit Rig – the epitome of innovation in the world of cup dab rigs.
