The Hammer Bubbler from GRAV was designed by Dave Daily.
This beautiful piece is made with 32mm tubing.
The outer body of this bubbler is clear glass while the mouthpiece, downstem, and feet are colored glass.
It was designed to cool and filter smoke through 1.3cm of water.
GRAV is based in Austin Texas. It made a name for itself for producing high-quality hand made glass bongs and pipes for affordable prices.
Their concept is to purely concentrate on producing the most scientific glass pipes and bongs on the market.
They do this by collaborating with some of the most well-respected glass artists in the world to create unique designs that you cannot find anywhere else.
