Mitsubishi Pencil Gel Ballpoint Pen Uni-ball One 0.5 Black Barrel 5-Pack UMNS055PBK.24 Ink StationeryOffice Supplies

This is a 5-pack of Uni-ball One. 【Product Features】 A gel ink ballpoint pen using technology with bead pack pigment, allowing for darker writing that is easier to remember. It stands out on paper. 1: The black ink is darker, and the colors are more vivid, producing clear and memorable writing. Compared to typical gel inks, the black color is more intense. Research conducted in collaboration with Ritsumeikan University has shown that darker and clearer writing is easier to remember. 2: The ink is quick-drying and does not smudge. The newly developed "Uni-ball One Ink" changes the ratio of solid to liquid components in the ink, allowing the liquid to quickly penetrate the paper while leaving the solid colorant on the surface. 3: Ink colors that can be hidden with a red sheet are also available. For those using a red sheet for memorization, the 0.38mm size offers three colors: orange, baby pink, and yellow, while the 0.5mm size offers orange and yellow, which can be concealed with the red sheet.
