The Phoenix Rising Twist Dome Base Bong is crafted from quality glass blown in the USA. The clear glass construction forms a single round chamber elevated on the dome shaped base for a touch of elegance. The neck of this piece is the real show stopper, with a built-in twist diffuser that cools your smoke and looks amazing while in use! Each bong includes a grommet style herb slide connection and downstem. Grommet colors vary.
