GRAV® Coffee Mug Pocket Bubbler | Mini Two-Hole Perc Bubbler | 10mm
The GRAV® Coffee Mug Pocket Bubbler is a compact water pipe shaped like a coffee mug, roughly half the size of GRAV's full-size Coffee Mug Bubbler, with a two-hole percolator downstem that cools smoke in shallow water. It uses a 10mm cup bowl and includes an angled 45-degree mouthpiece to prevent splashback, with six colorways available.
Best for: On-the-go smokers who want water filtration in a pocket-sized piece

Why Choose the Coffee Mug Pocket Bubbler
Compared to a dry hand pipe, the two-hole percolator adds real water filtration, cooling smoke before it reaches you rather than pulling it straight and hot. It's roughly half the size of GRAV's full-size Coffee Mug Bubbler, trading some water volume for portability and discretion, and the 45-degree angled mouthpiece cuts down on splashback while letting you see and light the bowl without hovering directly over the flame. Because the 10mm cup bowl can be swapped for a 10mm 90-degree quartz banger, one piece easily covers both dry herb and concentrates instead of needing two separate setups.
Ideal For
This bubbler suits smokers who want the smoother pull of water filtration without carrying a full-size piece, and anyone who wants one compact rig that can flex between dry herb and dabs.
Care & Maintenance
Change the water after each session — shallow-water percolators foul faster than deep-water pieces since there is less volume to dilute residue. Remove the bowl and downstem before cleaning. Soak in isopropyl alcohol with coarse salt, focusing on the two percolator holes, then rinse thoroughly with warm water. Let the glass reach room temperature before rinsing to avoid thermal shock.
