Glass Bubbler

The HAMR is a handheld cold start rig for consuming concentrated cannabis. This all-in-one setup streamlines a formerly complicated process by centralizing all of the necessary pieces into one unit.

The GRAV® Upright Bubbler is 7" tall and made on 44mm tubing. Its fission downstem diffuses smoke through water and is fixed inside the bubbler to prevent damage.
