The Coffee Mug Bubbler by Grav is the ultimate wake-and-bake companion. Part of the GRAV Sip Series, this cleverly designed piece looks like your favorite mug but conceals a powerful internal bubbler. The smoke pathway and fixed fission downstem are built into the handle, delivering a smooth, filtered hit with every pull.

With great hand-feel and a generous chamber, the Coffee Mug Bubbler is designed to be as pleasant to use as it is to look at. Standing 4 inches tall to the rim and 7 inches to the top of the straw, it’s compact enough for daily use but unique enough to stand out in any collection. Comes ready to go with a 14mm cup bowl for dry herb.
