Hancept Zero MK2 Pen Transforms from Flat Credit Card to Writing Instrument in Seconds

Sure, Facebook AI can emulate your handwriting, but nothing can beat the real thing, that is unless, you’re spending a fortune on the Hancept Zero MK2. Touted as “the world’s only card-sized pen that transforms,” this foldable pen is just 2mm thick when flat—about the thickness of two stacked credit cards—making it slim enough to slip into a wallet.

Not just for looks, it features a chassis crafted from 6000-series aluminum alloy, 316L stainless steel, POM (a durable plastic), and N52 neodymium magnets. All of these components come together in a mechanism involving 54 precision-engineered parts, allowing it to unfold and snap into a hexagonal pen shape in seconds (about four, to be exact). Despite its shape, the hexagonal grip is designed to be ergonomic, and it weighs under an ounce (28g) to boot, keeping it lightweight for everyday carry (EDC).

The pen’s transformation relies on a magnetic folding mechanism, which not only makes it functional but also adds a tactile, almost playful element to the experience. It’s billed as a blend of craftsmanship and innovation, inspired by the precision of luxury automatic watches. How much?
