This glass recycler dab rig features two barrel-shaped chambers, the tubing located on the back of the dab rig connects the two chambers together. When you inhale the smoke/vapor(depending on whether you use it as a bong or a dab rig) will be diffused and fully mixed with water for maximum filtration and cooling down the temperature of the smoke/vapor. The unique structure of this dab rig makes it impossible for a drop of water to get into your mouth no matter how big a toke you're taking.
