16 Inch Og Glass Water Pipe by Daze Glass - PipeThis 16 inch OG super thick glass water pipe was designed by us here at Daze Glass. It's made with a simple design which is thick enough to withstand some bumps and bruises. At 9mm in thickness, this pipe is almost double the thickness of a typical 5mm water pipe. Functionality is highlighted by the diffused downstem, which provide filtration for your smoke and a 3 prong ice pinch catcher which allows you to stack some ice cubes and cool your smoke.
