Klein bongs and dab rigs are those with a special type of recycling function, in which water is brought outside of the rig and then back into the main chamber. These Klein recyclers often start by acting as a sort of splash guard, stopping water from being pulled into the neck, and then draining this water through the tube back into the primary chamber. We have a variety of Klein recycler bongs, Klein dab rigs and other Klein recycling water pipes.
