Airflow focused for seriously powerful puffs. So you’ve stumbled across the magic of STAX and now you’re looking to take it to heavenly levels with the perfect base? Well, look no further! While all of GRAV’s designs are nothing short of superior, this particular straight bong base stacks up even higher than the rest. The world-renowned (and Austin-based) glassmasters have created an incomparable piece: it’s flared base makes it stable nor how sky-high you STAX, while a disc perc keeps it bubbling for unstoppable airflow. When you plan on popping on a few more inserts and a mouthpiece, this borosilicate glass piece will keep you from having to strain from restricted hydrodynamics. It’s even further stabilized by a two-pronged Dewar’s joint for extra protection against breakage. You’ll love how easy to reach the disc perc is for quick and simple cleanings that let you get to all those little nooks normally just out of reach!
