A feat of precision once reserved for jet engines, the MK3 Steel MetMo Cube is the most over-engineered desk toy you can own. The MK3 refines the formula with upgraded 316 stainless steel, improved pneumatics, and ultra-fine machining tolerances to achieve the most polished design yet. Simply flip the cube and let gravity take over as air escapes at a perfectly controlled rate — transforming physics into a pocket-sized moment of meditative calm.
