XMAX Starry & XVAPE Fog Pro Glass Bubbler gives you the option of turning your XMAX Starry 3.0, XMAX Starry 4 or XVAPE Fog Pro Dry Herb Vape into a Shisha-type vaping device. The glass bubbler and extention pipe connect to the Fog Pro Mouthpiece or Starry 3.0 Mouthpiece after you fill the glass bubbler with water. Then you dry herb vape, drawing vapour through the XMAX Glass Bubbler filled with water.
