Key Features and Benefits:

• Smooth skip-free writing experience
  Cellulose nanofibers give the acid-free ink a perfectly smooth skip-free writing experience with 50% less viscosity than conventional ballpoint pens. That means it’s hard to blur even in fast writing and prevents excess ink flow. Step into the future of rollerball pens and enjoy smooth, permanent writing with the SIGNO 307 gel pen.
• Archival-quality Super Ink
  Uni-ball’s innovative Super Ink technology is the world’s first practical application of cellulose nanofibers. Cellulose nanofibers are a next-generation plant-derived material being developed for uses in various industries. Used as a thickening agent in the pens, it increases the smoothness of ink so that the pens remain skip-free even when you write fast.
