The GRAV Hammer Bubbler is 4" tall and made on 32mm tubing with an etched label. The bubbler's body is transparent, while the mouthpiece, downstem, and feet are colored glass. Its fission downstem diffuses smoke through water, and its feet stabilize the bubbler between uses. No accessories are necessary for using this bubbler, and it functions best with approximately 0.5" of water. Specs: 7" long 32 mm Carb featured on the left Designed by Dave Daily
