## Description

These gel ink ballpoint pens use new bead pack pigment technology to make it possible to write darker text, which has been proven effective in making it easier to remember. Clear text in your notebook.Uni-Ball One. 1: Black is darker and the colors are more vibrant, letting you write clear text that’s easy to remember. The black color is even darker than general gel ink.In collaboration with Ritsumeikan University, we have found that the darker and clearer text written in black ink is, the easier it is to remember it.You can write text that will easily leave an impression on you when you review your notebook.2: Non-smearing/quick-drying ink: The ratio of the solid and liquid content in the newly-developed "Uni-Ball One Ink" has been altered, allowing the liquid ingredients to penetrate the surface of the paper quickly while leaving the solid color material on the surface.While it’s quick-drying ink that penetrates the surface of the paper quickly, it does not smear or bleed through since it suppresses the color material from being absorbed into the surface.3: A lineup of ink colors that can be concealed by red sheet underlays: For those who use red sheet underlays for memorization as part of their memory learning process, these underlays can be used to conceal 3 colors of ink (orange, baby pink and yellow) in the 0.01-inch (0.38 mm) diameter set of pens, and 2 colors of ink (orange and yellow) in the 0.02-inch (0.5 mm) set.
