This Rock Glass Showerhead perc bubble base bong features a unique design to maximize flavor and filtration. The bent neck design prevents water from reaching your mouth even in this small piece and the narrow design condenses the flavor of your smoke or vapor. The showerhead perc gives you incredible diffusion without any drag. Watch as the inner bubble chamber fills with smoke before being pushed into the bent neck. This piece features a hollow base to allow for more water and better smoke cooling. Featuring a 18mm female joint this piece includes a 14mm bowl piece.
