The 12 inch beaker pipe from Grav has one purpose, kicking the crap out of your lungs every time you pick it up. It's a simple but effective combo, the removable diffused downstem feeds into a massive beaker base which provides a huge amount of capacity for you to milk it up hard. Then there is the Grav Labs signature ice pinch which allows you to drop in a few cubes to bring the hit down to super cool temperatures. The downstem is fitted with a 14.5mm female ground glass joint and they include a 14.5mm male bowl to match.
