Japanese toymaker MegaHouse has unveiled a miniature Rubik’s Cube — one so tiny that you might need a pair of tweezers to solve it, reports CNN.

Each face of the cube, which is made from aluminum, measures about five millimeters (around 0.2 inches) across. It was made available for pre-order on the manufacturer’s website on last week, with deliveries expected next April.

The miniature model breaks the record set by British puzzle designer Tony Fisher in 2016, when he startled fans with a 5.6-milimeter version.

But the price tag suggests it’s likely to be a collector’s item rather than the kind of cube that players fiddle with on the go.

They are being sold at 777,777 yen ($5,320), and each comes with a stand declaring it the “World’s record smallest Rubik’s Cube."
