The MJ Arsenal 4 Piece Grinder is a durable preparation accessory engineered to reduce dry materials and botanicals into a smooth, consistent texture. While the manufacturer is primarily recognized for its extensive line of glassware, this standalone device is fabricated entirely from lightweight aluminum. Designed for daily botanical preparation, it features a threaded, multi-chamber construction that separates the grinding, holding, and sifting processes into distinct compartments. The device offers a highly reliable mechanism to process materials for various applications. It appeals to users seeking a pocket-sized and portable tool without compromising on interior capacity or structural integrity.
Four-Tier Threaded Design
Operating as a complete preparation system, the device divides the shredding, storage, and sifting phases into four distinct compartments. The middle storage section securely houses the freshly processed materials as they fall through preset openings. Below the holding compartment, a woven metal screen acts as a sifter to separate fine particles, which accumulate in the bottom collection chamber for separate preservation.
Diamond-Cut Shredding Teeth
The upper section is equipped with sharp, diamond-cut teeth engineered to shred botanicals efficiently while preventing the material from bunching up. This top cap connects to the main body via a secure magnetic lid connection. The strong magnet keeps the upper chamber firmly attached during the twisting motion, ensuring that the enclosed contents remain safely contained throughout the entire preparation process.
Compact Aluminum Construction
Fabricated completely from metal, the grinder offers exceptional durability while maintaining a highly travel-friendly profile. It features a standardized 2.2-inch (56 mm) diameter, providing ample interior capacity within a compact overall footprint. These dimensions classify it as a convenient, pocket-sized tool that fits effortlessly into standard travel bags or small storage containers. It is also manufactured in assorted colors like black, blue, green, and purple.
