Broke your downstem? Don’t sweat it—our collection has you covered.A downstem is a vital piece of glass that fits into your bong’s joint and carries smoke from the bowl into the water chamber for filtration. In other words, it’s the piece that makes everything happen. Because downstems come in various lengths and sizes, it’s vital to check your measurements before buying a new one. Be sure to consult our Guide To Choosing A Downstem beforehand so you don’t end up with the wrong fit.
