The Hammer Bubbler from GRAV. Available with 32mm or 25mm bubbler bodies and come with the unique X-Cut design diffused downstem. Each self-standing bubbler comes with a deep one hole push bowl, GRAV logo, and roll stop feet.
Can't use a screen so it gets dirty quick. Requires constant, complex cleaning. Spills easily and frequently when packing bowl. Great way to sip bongwater. Got the 3 inch thinking mini would be too small but 3 inch is tiny. Could have used a web of glass reinforcement at the weak right angle mouthpiece connection. Pricey too! P.S. Never did get 15% off any purchase for last review I wrote.
