In the past few years, we have covered plenty of fancy magic cubes here. The CubeLab Mini 3×3 Cube is the smallest one we have seen. It is designed to work like a normal Rubik’s Cube. It measures only 0.4 x 0.4 x 0.4 inches.
This tiny Rubik’s Cube is tiny enough to fit on the tip of your finger. It has an ABS construction. You can find out more about it here.
