Experience crisp, vivid handwriting with the revolutionary Uni-ball ONE Gel Pen 0.38mm (8 Colors Set). Formulated with a newly developed "bead-pack pigment" ink technology, the Uni-ball ONE keeps its color pigment on the paper's surface rather than absorbing deep into the paper fibers. The result is extraordinarily rich, dark, and vibrant lines that leave a lasting impression. In fact, joint research with Ritsumeikan University proved that studying with the deeper, clearer black ink of Uni-ball ONE makes notes significantly more memorable.
The advanced fast-drying ink formula balances liquid and solid components so the liquid quickly penetrates the paper while preventing smudging, ghosting, and bleed-through—making it ideal for daily journaling, note-taking, and left-handed writers. For students and planners, specific colours are engineered to be hidden when covered with a study red memorization sheet.
Eight Colours include: Black, Blue, Sky Blue, Green, Orange, Red, Pink and Blue Black.
