This slender, straight tube bong measures only 20 cm in height, heat resistant borosilicate glass. The clear glass mini bong comes equipped with a 14.5mm ground joint and a removable glass down stem with a fixed herb bowl. We recommend placing a metal screen in the bowl to prevent unwanted herb crumbs or ash from traveling into the bongs water. A carb hole can be found on the lower part of the tube for extra control of your hits and the circular foot provides great stability. The bongs thick, rimmed mouthpiece feels comfortable and the solid construction means this affordable bong will last for years if looked after and maintained correctly.
