Grav Circuit Rig Bong

The Circuit Rig is a unique glass Dab Rig from GRAV designed by Justin Couturier.

It has an air intake hole set into the body of the rig at an angle, creating a rapid spin effect and powerful centrifugal force.

It features two twin chambers stacked on top of each other to create the Circuit effect.

The sharp bend in the mouthpiece prevents water from any contact with the user’s lips. 

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.
