Grav mini upright bubbler is 6″ tall and made on 32mm tubing. Its fission downstem diffuses smoke through water and is fixed inside the bubbler to prevent damage. Its angled mouthpiece acts as a splashguard, and its lip wrap is tooled for comfort. No accessories are necessary for using this bubbler, and it works best with approximately 1.5″ of water. Probably the favorite bubbler in our lounge right now, perfect draw, flared mouthpiece, great diffusion, a carb in just the right location and a very clean almost minimalist art design.
