9″ GRAV® upright bubbler made on 50mm glass with black accents, fixed fission downstem, flush Dewar sealed joint, 14mm funnel bowl, angled mouthpiece, and tooled lip wrap.
The large GRAV upright bubbler is 9″ tall and made on 50mm tubing with black accents. Its fission downstem diffuses smoke through water and is fixed inside the bubbler to prevent damage. Its Dewar sealed joint is flush with the body of the bubbler, maximizing the pipe’s internal volume. Its angled mouthpiece acts as a splashguard, and its lip wrap is tooled for comfort. The upright bubbler comes ready to use with a 14mm funnel bowl and works best with approximately 2″ of water.
