It takes a great amount of workmanship to produce a water smoking pipe with a coil tube. The coil tube acts to cool the smoke out for a smoother smoke. The smoke is forced to go through a long pathway and travel a long distance via the coil. The pipe finishes off with a bulb perc for enhanced cooling. This pipe comes with ice catcher notches and glass beaded accents. The joint size of the water pipe is 19mm and includes a 19mm to 14mm slotted downstem. It also includes a 14mm color matching bowl. Diameter of water chamber is 4.25 inches. Diameter of the mouth end is 2 inches.
