We stacked up two functions with the Stack Pipe! This silicone glass piece was designed to be used as a bong AND a dab rig, so we included a flower bowl and a quartz banger. Simply swap your accessory, and maybe change the water, to switch between functions. This piece is made up of a silicone body piece and several glass accessories that keep the smoke tasting clean and pure, and gives the piece its shape and structure. It has a larger, main water chamber, and a second glass tube in the downstem. Watch the smoke milk in the chambers until you've created the perfect-sized cloud. Then just pull the slide and take a rip!
