This 4.5" fission downstem from GRAV allows to add powerful diffusion to any 18mm beaker or straight-based water pipe with an angled joint. This downstem has fissure holes to diffuse the smoke through water for smoother inhales. 

To ensure that the fissure holes have smooth edges to reduce clogging, the holes were made with a tungsten rod while the glass was hot. When you add this fissure downstem to your setup, you'll appreciate the improved smoking experience. No more coughing and settling for harsh, mediocre hits. 

This downstem with fissure holes is sure to become your most used smoking accessory. It's another quality product from GRAV that's designed to take your smoking experience to the next level.
