Grav Labs 4" Hammer Bubbler- 32mm Glass

Grav Labs

From Grav Labs and available at 421Store, the GRAV Hammer Bubbler stands 4 inches tall, crafted from robust 32mm tubing. It features a stylish etched label, adding a touch of elegance. The bubbler's main body is transparent, while the mouthpiece, downstem, and feet are highlighted with vibrant colored glass. 

This piece is engineered with a fission downstem to effectively diffuse smoke through water, ensuring a smooth smoking experience. Its feet provide stability when it's not in use. Conveniently, this bubbler doesn't require any extra accessories and functions best with about 0.5" of water.
