Add a vortex to your STAX build.

The STAX collection from Grav Labs is the first modular water pipe series available on the market. That means you can tailor your pipe yourself, for a personal fit. Add percolation, dial in airflow, and build your bong as tall as you want. All with the same quality glass you expect from Grav Labs. 

This mouthpiece is made with "Helix" technology. Designed with three angle tungsten holes that cause the smoke to spin upwards and aerates your draw as you inhale. Smoke won't be as heavy for a better smoking experience.
