Phoenix Star 17 Inches Percolator Bong Funnel-shaped & 4 Arms Perc PHX532, constructed of high quality borosilicate glass, is decorated with American Northstar Glass Rod to offer you and your customers pretty outlooking. The glass bong comes with 17 inches in height and 5mm thick big round base for stability. And there is a funnel shape design in the straight tube. This water pipe is equipped with a four arms perc to diffuse the smoke for better filtration. The smoke passes through the undetached downstem to the four-arm perc to be diffused and filtered to create more bubbles and more interactive space with water for the smoother flavor. The bubbling water from the transparent glass can make you quiet and relaxed.
