This is a 14mm showerhead ash catcher from Cheech Glass set at a 45-degree angle, with a flower design etched into the glass by sandblasting for a frosted, textured look. It sits between your bowl and your bong, trapping ash and debris before they reach the main piece and adding a round of showerhead diffusion for smoother hits. It runs 14mm male to 14mm female, so check that against your piece. It's built in borosilicate glass. A good-looking, practical add-on for a 14mm water pipe.
