ZAI

ZAI is a South Korean stationery brand built around a single idea: a pencil that never needs sharpening. Its Carbon Pen compresses pencil lead into a solid core that writes like graphite but wears far more slowly than a conventional pencil, so the body keeps working through hundreds of refills and no wood has to be cut.

The brand was developed inside Seoul studio one+design/MW, whose CEO and creative director Wan-sup Kim oversees product design and overseas operations. The pen is machined in aluminium with a hexagonal grip and offered in pencil and sharpener formats; it is distributed through stationery shops across China and was presented at the DDP Design Launching Fair during Seoul Design.
