This is an 8" bent Neck water pipe with ideal filtration. The base chamber has a single honey comb diffuser which creates maximum airflow throughout the. piece. Honey Comb diffusers are one of the most efficient and smooth-hitting diffusers available. The many tiny openings in the diffuser yield more smoke per volume of air in one inhalation. This is the benefit of maximum diffusion. It produces a steady and evenly distributed ingestion of smoke or vapor.
