Phoenix Star Percolator Bong with 8 Arms Perc 17 Inches PHX613 is constructed of borosilicate glass and measures 17 inches tall with balloon shape in the middle. Its diffused downstem with slits is detachable, so it is convenient to replace and clean. The glass bowl is tightly connected with downstem by a keck clip to avoid movement. This glass percolator bong is equipped with a 8-arms perc, which is helpful to filter your smoke for better flavor. After passing through the downstem, smoke rises to 8 arms perc to be decomposed to create more bubbles and more interface areas with water for smoother hits. You can watch the water rolling and bubbling for fun by the transparent glass. And this percolator bong also comes with ice catchers. You can put ice cubes from its mouthpiece for cooler hits.
