Black Sheep has taken the standard beaker base bong and improved it in every way possible. This 14'' tall bong features a 14mm removable diffused downstem and a popped hole showercap perc at the base of the neck for extra diffusion. The grooved ice pinch allows you to stack ice for an extra level of cooling. This highly functional bong will be sure to please. Made by Black Sheep Glass in southern California using high quality borosilicate glass.
