Grav 4" V2 Hammer Bubbler 32mm

The GRAV® Hammer Bubbler is a mini, professional water pipe that diffuses smoke through water. At just 4 inches, it's made on 32mm tubing and is stabilized between uses with its feet. No accessories are necessary for using this bubbler, which functions best with approximately 0.5" of water.
