The GRAV® Coffee Mug Pocket Bubbler is the perfect addition to your morning routine. This pocket bubbler is made from thick borosilicate glass. The bubbler features a 10mm glass cup bowl, perfect for enjoying just the right amount of your favorite dry herbs.
The GRAV® Coffee Mug Pocket Bubbler has a unique design resembling a miniature coffee or espresso cup. The shape adds whimsy to your smoking experience and is easy to loop a finger through and hold casually.
Not only is this pocket bubbler visually appealing, but it also provides smooth hits thanks to its aggressive percolator downstem. The percolator diffuses the smoke, cooling it down and making for a more enjoyable hit.
