This bong has a unique look to it, featuring an eye-catching stack of Swiss perc holes along the tall cylindrical chamber. Sitting at the bottom, a showerhead percolator provides smoke with effective water filtration to purify your hits. Pre-cooled smoke is pulled up through the Swiss percolators as you inhale, providing extra cooling power as the smoke is forced around small channels to remove any remaining heat from your hits. This piece is medium-sized, narrow for easy handling, and constructed with durable borosilicate glass. All these features deem the Stack Swiss Bong is reliable daily driver for any smoker.
