MJ Arsenal is a Denver-founded cannabis-accessories company known for compact borosilicate mini dab rigs, blunt and joint bubblers, bongs and glass built for electronic rigs. Founded in 2016, it built its identity around small-format function and patented water-filter designs rather than cannabis products themselves.
Founding and the co-founder
MJ Arsenal began in Denver, Colorado in 2016 under the name Mary Jane's Arsenal. Josh Camitta is a co-founder; he came out of professional golf and sales and operations work for the PGA Tour, and in 2014 invented and patented The Grale, an earlier dosing-related device, before starting the MJA line.
The early product idea
Camitta's early work centered on compact water filters for rolled products, the blunt and joint bubblers. The Martian blunt bubbler became the recognizable original, and the company extended the same short-airpath idea into mini dab rigs.
Mini dab rigs
The rig catalog runs through models including Apex, Apollo, Atlas, Bloopcycler, Claude, Infinity, Jammer, Royale and Ursa. Designs vary in percolation, chamber geometry and styling, but the shared proposition is a shorter vapor path and a smaller footprint than a full-size rig. Joints are 10mm and 14mm.
Bongs, bubblers and hand pipes
The flower-oriented line includes bongs, blunt and joint bubblers, hand pipes and water pipes, with named collections such as the outdoors-inspired Alpine Series. The broader catalog adds carb caps, terp pearls, grinders, torches, ashtrays, storage and cleaning tools, which makes the brand a general accessories shop rather than a single-product company.
Electronic-rig compatibility
MJ Arsenal makes glass tops, bubbler attachments and hose pieces for the Puffco Peak, Peak Pro, Pivot and Proxy and for Carta and Carta Sport hardware. Named attachments include the Halo, Lasso, Fabcycler, Bridge and Medusa for the Peak family, Fab Egg and Plateau tops for the Pivot, and the Phantom Proxy water pipe.
Materials
The company builds in what it describes as 100% lab-grade borosilicate glass, with quartz used in some concentrate accessories. Borosilicate is the standard material for smoking glass because it tolerates thermal cycling better than soda-lime glass.
Issued patents
The company's patent notice lists utility patent 10,251,419, covering water-filter designs associated with The Martian, Dubbler, Commander, Jammer, Ursa, Claude, Royale, Infinity and Mini Jig. It also lists design patents D843,647 S for the Dubbler and D820513S1 for The Martian.
How it sells
MJ Arsenal sells directly online, through a store locator and through wholesale accounts, with free US shipping over $50, 30-day returns, a Terp Tokens rewards program and a Maker's Pass. Because it makes accessories rather than regulated THC products, it operates outside the cannabis licensing system that governs cultivators and dispensaries.
