Mitsubishi Pencil Gel Ink Ballpoint Pen uni-ball one Refill Refill 0.5mm Blue Black UMR05S.644902778298848 (10 sets)

A new gel ink ballpoint pen featuring newly developed gel ink and a simple, straight shaft design. Compared to regular gel ink, the black color is even deeper, allowing you to create impressive notes that stand out clearly when you look back on them later. *This is a refill. The ballpoint pen barrel is sold separately.

  The notes are clear. Adopts newly developed “Uniball One Ink”
  ​ Unlike general gel ink, it uses a new pigment that minimizes the penetration of colorants into paper fibers. The pigment used in Uniball One Ink is a uniquely developed bead-packed pigment that confines conventional coloring materials into particles. By trapping the pigment that serves as the coloring material in the ink inside the particles and increasing the size of the particles, we minimize the penetration of the coloring material into the paper surface. As a result, the coloring material on the paper develops its original color, and black becomes darker. You can write characters that will be memorable when you look back at your notes.

  ​ Quick-drying ink that doesn't bleed
  By changing the ratio of solid and liquid components in the ink, it is possible to quickly penetrate the liquid component into the paper surface while leaving the solid coloring material on the paper surface. Although it is a quick-drying ink that penetrates quickly into the paper surface, it prevents the coloring material from being absorbed into the paper surface, so it does not bleed or bleed through.
