Stündenglass specializes in making a unique hourglass style gravity bong that has quickly become an iconic smoking product. Stündenglass Gravity infuser hookahs have a classic hourglass shape, and use the gravity of water falling into the next chamber to pull smoke through a bowl and push that smoke through a hookah hose for inhalation. Truly a modern smoking experience. Shop for a new Stündenglass bong or check out some of our Stündenglass accessories such as stems, globes and even the new Modül!
