The Invincipole is a durable aluminum downstem that goes hand-in-hand with our Invincibowls
— makes sense that an unbreakable bong bowl should have an unbreakable downstem to complete the picture! Because conventional downstems are slender tubes that are made of glass, they are one of the most fragile parts of a bong. They break when dropped, being cleaned, or even when being inserted into the bong itself. We considered all of this when creating the Invincipole, a diffused downstem designed to overcome the shortcomings of glass.
