The Grav Sip series is modeled after everyday objects that also carry liquid. Each of these molded borosilicate glass pieces has been thoughtfully designed with style and function in mind. This familiar design conceals a really effective bubbler. The perc and smoke pathway are built into the mug's handle. Great hand-feel and an ample bubbler chamber combine to make the GRAV Coffee Mug one of the most pleasant using experiences in a long time..
The Coffee Mug is exactly what it appears to be. A cup-shaped bubbler with minimal filtration and the ability to be completely filled with water and have no splashback make this easy to hold pipe a clear winner.
