The MJ Arsenal Tetra Hand Pipe is what happens when a designer actually thinks about the hand pipe format. Created by Andy Roth, the Tetra's signature four-column midsection isn't just a visual statement, it gives you a natural, secure grip that makes every session feel intentional. The rounded chamber flows cleanly into a generously sized 19mm bowl, and the whole piece is crafted from 100% borosilicate glass built to handle daily use without complaint.

At 4.5 inches long it sits perfectly in hand, hits smooth and clean every time, and the open column design makes cleaning straightforward. No hidden chambers, no complicated geometry, just a beautifully engineered piece that performs exactly as it looks like it should.

Simple, refined, and built to last. The kind of pipe that makes everything else feel like a compromise.
