This scientific glass water pipe features dual honeycomb percolators. Together these two percs create optimal filtration for perfectly diffused smoke. If you are unfamiliar with the honeycomb percolator, you will certainly be pleased when you see how they function. These effective percs are shaped like disks, and have countless holes across their entire surface area. Each of these holes produces bubbles for filtration of smoke and water. For smokers who value the most optimal and thorough filtration, honeycomb percs are a suitable choice. The bong is hand blown from thick borosilicate glass, and has a wide base. Not only does the Double Honeycomb Perc Water Pipe stand stably on its base, the bong also features an 18mm female joint. If you've got a knack for style, then you probably want some choice when it comes to color. Luckily, this bong does have several color options!
