Japanese toymaker MegaHouse recently unveiled the world’s smallest Rubik’s Cube, an aluminum cube measuring only 0.19 inches per side and weighing just 0.33 grams, but with a price tag of $5,320.

To celebrate the 50th anniversary of the original Rubik’s Cube invented by Hungarian sculptor Erno Rubik, Japanese toymaker MegaHouse set out to create the world’s smallest Rubik’s Cube. The company came up with the idea for the project about four years ago and started working on it in 2022. Although making a metal square only 0.5 cm in width doesn’t seem that difficult in this day and age, making a functional Rubik’s Cube with rotating faces was a big challenge. MegaHouse had to team up with a precision-cutting company to ensure that all the tiny parts worked as intended.
