At a glance
MJ Arsenal is a Denver-founded cannabis-accessories company best known for compact borosilicate mini dab rigs, blunt and joint bubblers, bongs and compatible glass for popular electronic rigs. Founded in 2016, it built its identity around small-format function, accessible pricing and patented water-filter designs rather than cannabis products themselves.
Founding and the verified co-founder
MJ Arsenal began in Denver in 2016. Forbes identifies Josh Camitta as a co-founder and says the company was originally conceived as Mary Jane's Arsenal. Camitta previously worked in professional golf and developed an earlier dosing-related device before creating products under the MJA name. The current official site does not publish a complete founder or leadership roster, so additional founder names are not assigned here without stronger evidence.
The early product idea
Camitta's early work centered on compact water filters for rolled products, including blunt and joint bubblers. The Martian blunt bubbler became one of the recognizable originals, and the company expanded the same compact-airpath idea into mini dab rigs. This history explains why the brand's catalog is organized around small glass with engineered water paths rather than tall traditional tubes alone.
Mini dab rigs
The current rig catalog includes models such as Apex, Atlas, Bloopcycler, Claude, Gemini, Hydra, Infinity, Jammer, Royale, Titan, Turbine and Ursa. Designs vary in percolation, chamber geometry and visual style, but the shared proposition is a shorter vapor path and smaller footprint. Buyers still need to match the rig, banger and joint size rather than assuming every accessory fits every model.
Bongs, bubblers and hand pipes
MJ Arsenal now sells more than dab rigs. Its flower-oriented lineup includes bongs, blunt and joint bubblers, hand pipes, chillums and a gravity bong, with named collections such as the outdoors-inspired Alpine series. The product range also includes grinders, ashtrays, storage, cleaning tools, pouches and apparel, making the brand a broad accessories shop rather than a single-product company.
Electronic-rig compatibility
The e-rig category includes glass tops and bubbler attachments for devices in the Puffco Peak, Pivot and Proxy families and for Carta hardware. Compatibility is model-specific. A top made for a Peak is not automatically interchangeable with a Proxy attachment or a standard 10-millimeter glass joint, so the exact device generation and connection type should be checked before purchase.
Materials and care
MJ Arsenal describes its glass as lab-grade borosilicate, a heat-resistant material commonly used for smoking accessories. Borosilicate improves thermal durability but does not make a piece impact-proof. Regular cleaning, careful torch use and the correct joint size remain important, particularly for compact pieces where residue can quickly narrow airflow.
Issued patents
The company's patent notice lists utility patent 10,251,419 for water-filter designs associated with products including the Martian, Dubbler, Commander, Jammer, Ursa, Claude, Royale, Infinity and Mini Jig. Patent records name Josh Camitta as inventor and MJ's Arsenal LLC as assignee. The company also lists design patents D843,647 S for the Dubbler and D820513S1 for the Martian.
Community programs and collaborations
MJ Arsenal operates Terp Tokens rewards and has used programs such as Maker's Pass to involve customers and creators in product design. Its catalog also includes collaborations and limited-edition archives. Those programs are commercial community initiatives, not independent design awards, and should not be represented as juried recognition.
Retail model and research limits. Products are sold directly online, through a store locator and through wholesale accounts. Because MJ Arsenal sells accessories rather than regulated THC products, it is not a cannabis cultivator or dispensary and does not need a cannabis-production license for the catalog described here. No material independent product award was verified in the reviewed sources; the strongest documented achievements are the 2016 launch, category expansion and issued patents.
