The small GRAV® Hammer Bubbler is 3" tall and made on 25mm tubing with an etch label. The body of the bubbler is clear while the mouthpiece, downstem, and feet are colored glass. Its fission down stem 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.
Available in several color options. After your order is placed, we will reach out to confirm your color selection.
