GRAV Coffee Mug Pocket Bubbler – Mini Glass Mug with 10mm Bowl

The GRAV Coffee Mug Pocket Bubbler is a miniature glass mug that works as a water pipe — about half the size of GRAV's full-sized Coffee Mug Bubbler, at roughly half the price. A two-hole percolator downstem cools smoke through shallow water, and a 45° mouthpiece with a downward-angled tip lets you tip the piece away from your face while lighting. It ships with a GRAV 10mm Cup Bowl, and a 10mm 90° banger turns it into a mini dab rig. Break-resistant borosilicate with a real glass handle. $49.99 at Angies Boutique in Los Angeles.

⚡ At-a-Glance Decision Summary

• What it is: A pocket-sized borosilicate bubbler shaped like an espresso mug, complete with a working glass handle.
• Why choose it: Half the size and roughly half the price of the full Coffee Mug Bubbler, with the same idea intact.
• Standout detail: The mouthpiece hole angles slightly down, so you tip the mug away from your face while lighting rather than toward it.
• What's included: A GRAV 10mm Cup Bowl. Ready for flower out of the box.
• Also a dab rig: Swap in a 10mm 90° quartz banger and it becomes a mini rig.

🧠 Our Verdict

The GRAV Coffee Mug Pocket Bubbler is a strong recommendation if you want water filtration in something genuinely small, and you like the joke. It is not a compromised version of the full-size mug — it is a properly engineered small piece, with a two-hole perc, a splash-proof mouthpiece and a glass handle that actually works. At $49.99 it costs about half what the full Coffee Mug Bubbler does. Buy the big one if you want a centrepiece; buy this one if you want something that lives next to the kettle.

Quick Summary

The GRAV Coffee Mug Pocket Bubbler is a mini borosilicate bubbler shaped like a coffee or espresso cup, about half the size of GRAV's full Coffee Mug Bubbler. It uses a two-hole percolator downstem in shallow water and a 45° mouthpiece angled down at the tip. A glass handle gives you somewhere to loop a finger. It includes a GRAV 10mm Cup Bowl and is available in clear and three colourways at Angies Boutique. $49.99.

GRAV Coffee Mug Pocket Bubbler – Mini Glass Mug Bubbler with 10mm Bowl

It is a coffee mug, and it is a bubbler, and it is small enough to lose in a coat pocket. GRAV describe it as about half the size of their full-sized Coffee Mug Bubbler — an espresso shot rather than a full cup. The mug body stands roughly as tall as a standard lighter, which our size-comparison photo shows directly.

The engineering is real, not decorative. A two-hole percolator downstem breaks smoke up through shallow water — you need very little in a chamber this size. The 45° mouthpiece keeps splashback away from you, which matters far more on a small piece than a large one because the waterline is so close to the lip.

The best detail is one most people miss. The hole at the tip of the mouthpiece is angled slightly downward. That means you tip the mug away from your face while you light the bowl, instead of tilting a flame back toward yourself. It is a small piece of thinking that you notice every single time you use it.

The handle is a real glass handle. Loop a finger through it and the piece sits securely in one hand — genuinely useful first thing in the morning, which is the entire premise of the design.

It ships with a GRAV 10mm Cup Bowl, so it works for flower immediately. Add a 10mm 90° quartz banger and the same mug becomes a mini dab rig.

Summary: The GRAV Coffee Mug Pocket Bubbler is a properly engineered mini bubbler shaped like an espresso mug, with a two-hole perc and an included 10mm bowl.

⭐ Who This Product Is For / Not For

Ideal For:

• Anyone who wants water filtration in something genuinely small. This is a pocket piece that still bubbles.
• Morning smokers. The design premise is a mug by the coffee pot, and the handle makes that work one-handed.
• People who liked the full Coffee Mug Bubbler but not the $97.99. This is the same idea at roughly half the size and half the price.
• Desk and bedside use. Small enough to leave out without it dominating the surface.
• Anyone who wants a mini dab rig too. A 10mm 90° banger converts it — our GRAV Seamless Quartz Banger in 10mm 90° is a direct fit.
• Gift buyers. It is a conversation piece that also works properly.

Not Recommended For:

• Group sessions. The chamber is espresso-sized. For passing round, the full-size GRAV Coffee Mug Bubbler or a proper bong is the right tool.
• Anyone wanting heavy percolation. A two-hole downstem in shallow water is effective for the size, but it is not a stacked-perc piece.
• 14mm accessory owners. This is 10mm. Your 14mm bowls and bangers will not fit.
• Anyone who wants big hits. Small chamber, small pulls. That is the format.
• Rough handling. Borosilicate is break-resistant, not unbreakable, and this is a small piece with a thin handle.

⚠️ Known Limitations

• It is 10mm, not 14mm. The included bowl is a 10mm Cup Bowl, and any banger you add must be 10mm. Most bong accessories people already own are 14mm.
• Small chamber, small hits. GRAV's own framing is "an espresso shot worth" — that is the point, but it is not a bong.
• Shallow water needs watching. There is very little margin between too little and too much in a chamber this size.
• The glass handle is a thin point. It is the most exposed part of the piece.
• Only Clear is in stock. Light Cobalt, Amber and Pink are listed but currently at zero.
• No banger included for the dab-rig conversion.

Summary: The GRAV Coffee Mug Pocket Bubbler is a 10mm, small-chamber piece — deliberately compact rather than compromised.

⚙️ Features & Benefits

• Two-hole percolator downstem: Breaks smoke into streams through shallow water, so a chamber this small still cools properly.
• 45° mouthpiece: Keeps splashback away from you, which matters more on a small piece because the waterline sits close to the lip.
• Downward-angled mouthpiece tip: Lets you tip the mug away from your face while lighting instead of tilting a flame back toward yourself. The detail you notice every session.
• Working glass handle: Loop a finger through it for a secure one-handed grip.
• Break-resistant borosilicate: GRAV's own description, and it takes an isopropyl soak with no coating to strip.
• Includes a GRAV 10mm Cup Bowl: Ready for flower out of the box, with a maria grip so you can pull it hot.
• Converts to a mini dab rig: Add a 10mm 90° quartz banger and the same piece handles concentrate.
• Part of GRAV's mini Sip Series of drinkware-shaped pocket bubblers.

Summary: A two-hole perc, a splash-proof angled mouthpiece and a real glass handle make the Coffee Mug Pocket Bubbler function as well as it looks.

📐 Structured Specs

🔌 Compatibility & Requirements

• Joint: 10mm female. This is the single most important spec — most bong accessories are 14mm and will not fit.
• Included bowl: A GRAV 10mm Cup Bowl. Spares and replacements are the GRAV Cup Bowl in 10mm.
• To dab: Add a 10mm 90° male banger. Our GRAV Seamless Quartz Banger in 10mm 90° is a direct fit and in stock.
• Not compatible with: 14mm, 18mm or 19mm bowls and bangers, or any 45° banger — the joint is 90°.
• Water: Shallow. Cover the downstem holes and no more — there is very little margin in a chamber this size.
• Required: Water and a lighter for flower, or a torch if you fit a banger.

🧼 How to Use & Troubleshooting

1. Add a small amount of water — just enough to cover the two downstem holes. Far less than you would use in a bong.
2. Seat the included 10mm Cup Bowl, or fit a 10mm 90° banger if you are dabbing.
3. Loop a finger through the glass handle and hold the mug steady.
4. Tip the mug away from your face as you light the bowl — the downward-angled mouthpiece tip is designed for exactly this.
5. Lift the bowl out to clear the chamber, then tip the water out after the session.

Problem → Solution:

• Water reaching your mouth: Overfilled. Cover the downstem holes and stop — a small chamber has very little margin.
• Harsh, dry draw: Underfilled, or the downstem holes are not submerged.
• Your bowl or banger will not fit: Check the size. This is 10mm, and most accessories people already own are 14mm.
• Awkward to light: You are tipping it toward yourself. Turn the mouthpiece away and the angled tip does the work.

Summary: Use less water than you expect and tip the mug away from you while lighting.

🧴 Care & Maintenance

• Empty the water after every session. A small chamber goes stale fast.
• Rinse with hot water for routine cleaning — most of the time that is all a piece this size needs.
• Isopropyl and coarse salt for a deep clean. Plain uncoated borosilicate with nothing to strip.
• Pull the bowl and clean it separately. The 10mm Cup Bowl comes out.
• Pre-saturated swabs such as Dr. Dabber Iso-Snaps reach the mouthpiece and the downstem holes.
• Mind the handle when you shake it during cleaning — it is the thinnest part of the piece.

Summary: Empty and rinse the Coffee Mug Pocket Bubbler after each session and it stays clean with almost no effort.

⚖️ Comparison Table

The honest read: this is not a cheaper substitute for the full Coffee Mug Bubbler — it is a different-sized product with a different job. The full mug holds a real chamber's worth and works as a centrepiece; the Pocket version is for a quick hit next to the kettle and disappears into a pocket. If you want one piece to do everything, neither is the answer — the Medium Upright Bubbler at $59.99 sits in the middle with a 14mm joint.

Summary: Buy the Pocket Bubbler for portability and quick hits; buy the full Coffee Mug Bubbler if you want the centrepiece.

💬 Common Questions & Answers

How is this different from the regular Coffee Mug Bubbler?
Size and joint. GRAV describe the Pocket version as about half the size of the full-sized Coffee Mug Bubbler, and it costs roughly half as much — $49.99 against $97.99. The Pocket takes 10mm accessories where the full mug takes 14mm, so they do not share bowls or bangers. They are two different products, not two versions of one.

How big is it, really?
The mug body stands roughly as tall as a standard lighter — our size-comparison photograph shows it next to a Bic so you can judge for yourself. GRAV do not publish exact dimensions, and their own description is "about half the size of our full-sized Coffee Mug Bubbler" and "an espresso-shot worth". It genuinely fits in a coat pocket.

What joint size does it take?
10mm. This is the most important thing to know before buying accessories for it, because most bong bowls and bangers people already own are 14mm and will not fit. The included GRAV Cup Bowl is 10mm, spares are available in 10mm, and the dab-rig conversion needs a 10mm 90° banger.

Can I dab out of it?
Yes. Swap the included 10mm Cup Bowl for a 10mm 90° quartz banger and it becomes a mini dab rig. The banger is not included — our GRAV Seamless Quartz Banger comes in exactly 10mm 90° and is a direct fit. A small chamber suits low-temp dabs well, because there is less volume for vapour to condense in.

What is the deal with the angled mouthpiece?
Two things. The mouthpiece sits at 45° to keep splashback away from you, which matters more on a small piece because the waterline is close to the lip. Separately, the hole at the tip is angled slightly downward, so you tip the mug away from your face while lighting the bowl rather than tilting a flame back toward yourself. It is a small design decision you appreciate every session.

How much water does it take?
Very little. Cover the two downstem holes and stop. A chamber this small has almost no margin between too little water and too much, and overfilling is the one way to get a mouthful. Start with less than you think you need and add a drop at a time until it bubbles cleanly.

What colours can I get?
Angies Boutique lists Clear, Light Cobalt, Amber and Pink. GRAV also make it in Smoke and Lake Green. Currently only Clear is physically in stock — the three colourways are listed but at zero. Ask us and we will tell you what is arriving.
