The Dankstop Double Tree Perc Bong is the perfect daily driver to have. Thick glass and strong quality, excellent smoke filtration and air flow. This is a very durable and clean cut piece. It features two 9-arm percolators stacked on one another. Tree percs have slits in the arms of the "tree" therefore the more arms the better creating more diffusion and filtration. Additionally to the tree percs there is a 18mm to 14mm removable diffused downstem. The downstem contains slits at the end where it makes the most contact with water. This is an additional percolation system for the water pipe to enhance and optimize your smoking session with a thick milky smoke that is less harsh but heavy hitting simultaneously. It also features an ice pinch toward the mouthpiece allowing the user to drop cubes of ice in to even further cool down the smoke or vapor. Standing 11 inches tall on a pedestal base with a 45 degree angled bowl and all the percolation systems within, makes this a top notch daily driver especially for the limited time sale price!
