GRAV® Hammer Bubbler - Assorted Colors

The GRAV® Hammer Bubbler is the tool for the job. (If the job is jumbo hits and a super easy-to-clean design).

The Hammer has been redesigned with a wide 38mm can, so it rests easy when not in use. A fission downstem diffuses smoke through 0.5” of water for cooling…and in 11 comely colors, it looks good doing it.
