This inline tree perc bong is made with color changing luminous glass. It is hard to truly capture the beauty of this glass with a picture, just wait until you hold it in your hands. This piece features dual percolators for maximum filtration and smoke cooling. In the main chamber is a long inline percolator with about a dozen slits to break your smoke into lots of bubbles. Sitting above that is a tree perc for the second round of smoke cooling. In the highest part of the bong is a splashguard to prevent any water from reaching your mouth.
