This Smart Bong is a unique piece of glass art that will offer you an uplifting hit! It is made of a solid heat resistant borosilicate glass formed in the shape of a hollow base tube. You can place your favourite herbs on the detached bowl, that connects to a detachable chillum through a sure ground of 18.8mm diameter. The chillum is used as a diffuser, so that your smoke spreads into the tube and gets filtered by the water. What’ s more, a twisted glass line will break up your smoke. With the Smart logo featuring at the top of the tube the whole set-up ends up in a cosy mouthpiece ring.
