This is one of the latest high quality Grace Glass Bongs. Made of a heat resistant borosilicate glass, Double Drum Bong is formed in the shape of a hollow base tube. You put your herbs onto the bowl equipped with a handle for easily lifting it up. The bowl connects to a chillum through a sure ground of 18.8mm diameter. A double drum percolator will bubble up your smoke and a spashguard in the shape of a dome with slit holes will keep water off your mouth. Some ice noches will keep some cubes for cooling your smoke and a rubber kick hole will offer you the option of a different toke angle. The Grace Glass logo is imprinted at the front of the splashguard chamber. The tube ends up in a comfortable mouthpiece ring on top.
