Japanese toymaker MegaHouse has unveiled the world’s smallest functional Rubik’s Cube, a tiny puzzle measuring just five millimeters (0.2 inches) across each face. Made from aluminum, it weighs only 0.3 grams and comes with a hefty price tag of 777,777 yen (about $5,320), likely positioning it as a collector’s item. MegaHouse partnered with precision engineering firm Iriso Precision to bring this micro-cube to life, and Guinness World Records has certified it as the smallest rotating puzzle cube.The miniature cube in comparison to a standard one TM & Spin Master Toys UK Limited
