Grace Glass OG Series Umber Grip Bong – You can place your favourite herbs upon the 3 point bowl, which connects to a diffuser of 18.8mm diameter, used as a means of spreading your smoke into the water chamber so that it gets filtered by the water. It includes also a mushroom percolator, for bubbling up your smoke, and some ice notches that can hold a few cubes for cooling your smoke. With the Grace Glass logo featuring below the percolator, the bong ends up to mouthpiece ring through some delicately embossed graphics.
