Uni-ball Signo 307 Gel Ink Pen 0.5mm -Blue Ink [UMN30705.33]


Uni-ball signo 307 is the pen that uses a cellulose nanofibers first time in the world.

It was very popular and got high evaluation with “SKIP FREE” in North America sold ahead.


Uni-ball Signo uses new material fibre of the plant.

The cellulose nanofiber is a very fine material that is uniformly mixed in the ink, was the ink viscosity at the time of writing able to reduce about 50% than the conventional gel ink ballpoint pen.

That means it is hard to blur even in fast writing because the viscosity changes appropriately when writing.

In addition, less viscosity ink doesn’t remain in the pen tip it is works to prevent the accumulation of liquid.


This gel ink is also acid-free, water-resistant, fade resistant, and protects against fraud.

説明 『ユニボール シグノ 307』は、紙などと同じパルプを繊維幅3nm〜4nmまで細かく解きほぐした「セルロースナノファイバー 」。極めて細かな素材であるセルロースナノファイバーをインク内に均一に配合させることで、筆記時のインク粘度を従来ゲルインクボールペンよりも約50%低減することに成功しました。インクの粘度が適正に変化することで、速書きや左利きの筆記など、従来では描線がかすれやすかったさまざまな筆記状況においても、かすれやインク溜まりが生じにくい安定した筆記描線を書くことができます。
