Why We Love It

  • Permanent Aluminum Construction
    The durable aluminum shaft is built to last a lifetime, resisting breakage and providing a comfortable, balanced weight unmatched by plastic pens.
  • Extreme Waste Reduction (Refillable)
    The pen is designed to be fully refillable, directly eliminating the need to purchase and discard hundreds of disposable plastic pens.
  • High Quality, Made in Japan
    The product originates in Japan, ensuring high standards of manufacturing quality, precision in the nib, and lasting durability.

What to Keep in Mind

  • Requires Specific Cartridge
    The pen is designed for MUJI's specific aluminum round shaft ink cartridges. While efficient, it limits the user to one specific refill type.
  • Requires Simple Maintenance
    As a fountain pen, the nib benefits from periodic cleaning (running water through it) to maintain optimal ink flow and smooth performance.
  • Different Writing Feel
    The experience is different from a ballpoint. It requires a slightly lighter touch and different angle to allow the ink to flow smoothly.
