Solid Color Silicone Downstem | Purple | 3 Inch
This downstem from Entropy Labs is made from food-grade silicone, and it’s basically indestructible. A downstem is the central component of any bong. And let’s face it - accidents happen, and stems break. This one can’t and won’t. Whether you’re looking for a replacement stem or want a nice backup plan, you can’t really go wrong with silicone downstems - there are literally zero downsides.
This one diffuses your smoke and gets it nice and filtered, so you can enjoy the full flavor profile of your herbs while ripping monster hits. It features an 18.8mm to 14.5mm joint and is compatible with all 18.8mm female joints. Cleaning it is a total breeze - just shove it in the dishwasher.
This diffuser downstem is available in five different lengths - 2 inches, 2.5 inches, 3 inches, 3.5 inches, and 4 inches long. It also comes in black, blue, green, purple, red, yellow, or white. So, there will be a color and size that fits your preferences.
