The MIO is Kokuyo’s highest grade paper and will be a joy to fountain pen and regular gel pen users alike. The high quality paper feels smooth to the touch but has just the right roughness to give the writer good feedback while writing. Ink dries quickly on the paper and is difficult to smudge, making the notebook ideal for left-handers. Kokuyo also managed to produce thin paper (20% lighter than the standard Campus line) that won't allow ink to bleed through. Paper is archival safe in pH neutral, so won't yellow over time.
