The GRAV Large Round Base Bong pairs a spacious spherical water chamber with a tall straight neck for a classic design built around stability and smooth filtration. Standing 12 inches tall with a wide 5.25-inch base, this GRAV round base bong offers considerably more chamber capacity than its smaller counterpart while remaining easy to handle. The concave neck incorporates a grip pinch for added control, while the built-in ice pinch allows ice to be added above the chamber for additional cooling. A removable 4.75-inch downstem provides diffusion and can be taken out for easier deep cleaning or replacement, while the included 14mm funnel bowl completes the setup. Made from clear borosilicate glass with prominent GRAV branding, this 12-inch GRAV bong delivers a clean combination of traditional round-base styling and practical everyday features.
