The Hi Guy Glass VG is about 7 inches long and about 4 inches tall. It is made of thick-wall (2.5 mm wall) clear borosilicate glass from Schott Glass of Germany. Wall thickness varies from 2.5 - 5 mm, so it is very durable. It sits stably upright on a flat surface, so loading the bowl is easy. The ceramic filter is exactly the same as the filter used in the other VaporGenie pipes. The filter assembly top and bowl attach by a ground glass joint. The ceramic flame filter is held in place by a stainless steel retaining wire.
