The Martian is MJ Arsenal's original blunt bubbler — a 2.25-inch piece of borosilicate glass that puts water filtration on a rolled cone for $12. It adapts to almost any rolled item, doubles as a one-hitter, and disappears into a jacket pocket. For anyone who mostly smokes joints and blunts, it is the cheapest real upgrade on the shelf.
Most accessory upgrades ask you to change how you smoke. Buy a bong, learn the bowl, pack it, clear it, clean it, find somewhere to put it. The Martian asks for none of that. You roll exactly the way you already roll, seat the cone in the intake, and pull.
The water chamber does the rest — smoke travels through it before it reaches your mouth, and it arrives cooler and less scratchy than it does straight off the paper. That is the entire premise, and its simplicity is why the design has been imitated across the whole accessible-glass category.
The dimensions carry more weight here than any feature list. At 2.25 by 2.5 by 1.25 inches, the Martian is hand-sized in the literal sense — it sits inside a closed fist. That is small enough to live in a coat pocket, a bag pocket, or a glovebox without a case and without announcing itself.
MJ Arsenal also put a pendant hook on it, which sounds like a gimmick until you have carried one on a lanyard or clipped to a bag strap and realized the piece stops getting lost. Small glass has a way of vanishing into couch cushions. This one has somewhere to live.
Build is 100% borosilicate glass, the same lab-grade material used for scientific glassware. That matters for two reasons. Borosilicate handles thermal shock — the temperature swing from cold water to hot smoke, or from a sink rinse to a warm room — without the stress fractures cheaper soda-lime glass develops. And it cleans up completely. Isopropyl and salt, a shake, a rinse, and the piece is back to clear. On a bubbler this small, with this little internal volume, that cleaning cycle takes about a minute.
The carb hole placement is the detail most people notice second, after the size. It is positioned where your finger naturally falls when you hold the piece, rather than where it was easiest to drill. Combined with the dual-function carb cap — it runs as a standard cap or as a directional-airflow cap depending on how you seat it — you get real control over how fast the chamber clears.
The design is also spill-resistant, which is the practical difference between a piece you can pick up and move mid-session and one you have to treat like a full glass of water.
Who this is for: people who roll. If your default is a joint, a blunt, or a pre-roll from a dispensary, the Martian is a direct improvement on what you are already doing, and it costs less than the pre-roll. It is also a genuinely good first piece of glass — nothing to learn, nothing to break the budget, nothing to intimidate. And it works as a travel piece for people who already own real glass at home but do not want to bring it anywhere.
Who it is not for: anyone looking for a concentrate setup. This is a flower and rolled-goods piece, full stop. If dabs are the goal, MJ Arsenal's mini-rig line is the right aisle — the Hydra Mini Dab Rig and the Gemini Mini Dab Rig are both built around a 10mm joint and ship with a quartz bucket. If you want water filtration in a larger everyday format, the Abyss Bubbler is the step up, and the rest of the catalog lives at MJ Arsenal.
MJ Arsenal was founded in Denver, Colorado, and the brand describes its own principles as innovation, affordability, and functionality — which reads like boilerplate until you look at the price of this thing. Twelve dollars for patented, lab-grade glass that ships within a day is not a normal margin structure for the head-shop world, where the same shelf space usually holds imported glass at four times the price with no design behind it.
MJ Arsenal has defended the line with patents and trademarks, which tells you how much of the category tried to copy it.
The cultural read on the Martian is that it quietly closed the gap between the two ways people actually smoke. For a long time the rolled-cone side and the water-pipe side were separate worlds with separate rituals, and moving between them meant owning two setups and committing to one per session. The Martian collapsed that into a twelve-dollar object you can hold in one hand. It did not do it by being sophisticated.
It did it by being obvious, cheap, and right — which is usually how the durable products win.
