- Writes smoothly without skipping, even during fast writing
- Uses cellulose nanofiber technology for the first time in a pen to achieve consistent, smooth ink flow
- Ink viscosity adjusts during writing to prevent skips and ensure clean, continuous lines
- Reduced ink pooling, as the ink settles evenly on the paper and does not collect at the tip
- Pigment-based ink provides excellent water resistance and lightfastness, preventing smudging or fading
- Cellulose nanofiber material creates a fine, transparent gel that allows ink to flow evenly through the pen tip for exceptionally smooth writing
- Available in 0.38mm, 0.5mm, and 0.7mm tips

I love everything. It takes forever to arrive, but worth it! Love the pens. But I exchange the fill with other ones I also buy here and fit perfectly 👌.
