It is a mechanical pencil refill lead that is ideal for taking notes that you can look back over and over again.

Note 1) The amount of sebum, the amount of water, and the strength of contact will make a difference in the stain suppression result.

Characters do not easily bleed even when a marker is drawn

Even if highlighted, the spread of the lead powder is suppressed, so the characters do not easily bleed, and the paper surface stays clean.

Smudge proof manufacturing method

With conventional mechanical pencil leads, the fine lead powder that appears during writing floats around the lines drawn, and this spreads on the paper surface due to rubbing, causing dirt on the paper. The new developed mechanical pencil refill from UNI has succeeded in suppressing dirt by using the "smudge proof manufacturing method" that adheres the lead powder to the paper surface.
In addition, we have been developing based on our conventional products that realized "strong", "dark" and "smooth" at a high level by blending nanodiamonds, and with pencil leads that has the same features of our previous products becoming much better than before.
