The Ooze Stack Silicone Glass Water Pipe is quite an inspired take on the classic sherlock bubbler bong. Rigid colorful silicone is molded to create the base, mouthpiece, and 14mm female joint of the Stack Bubbler. Resting between the silicone molds are two separate glass chambers, the larger of which is the water chamber where your smoke will be filtered through a diffused silicone downstem. Like many of the pieces in the Ooze silicone glass product line, the Stack works wonderfully with both concentrates and dry herbs and includes both a 14mm male bowl and banger nail. This smoke Stack can do it all!
