The Rocketship bong comes with a diffused downstem and bowl that fit in the 14mm female joint. The diffused downstem filters and cools down your smoke through the slits at the end of the downstem. This forces your smoke through the water before you inhale it. Sitting above that is a three pinch ice catcher that allows you to add ice to help further cool down your smoke when smoking. The Snoop Dogg Pounds Rocketship is available in four different colors for you to choose from. This classic straight tube has a unique mouthpiece for an airtight seal for better smoking and flawless function.
