This Bullfrog Glass Bong is a very interesting piece of glass art! It is made of a bouncer base tube of 25cm height and 45mm diameter. You can place your precious herbs or tobacco onto the detachable transparent bowl, which connects to a detachable chillum through a sure ground of 14.5mm diameter. The chillum is used as a diffuser, for spreading your smoke into the water chamber, so as to get filtered by the water. With the Bullfrog logo featuring along the tube, the bong ends up in a comfortable thick mouthpiece ring through a bent neck that will offer you a comfortable grip in addition to a funny sense of smoking.
