Limited Edition Uni-Ball One Summer Yurumatope Pen Set - Premium Uni Mitsubishi Pencils for Writing, Journaling & Office Use

Key Features

• Bead-Packed Pigment Ink: Unlike conventional gel inks, uni-ball one uses a proprietary pigment that encases colorants within beads, minimizing ink absorption into paper fibers. The result: deeper blacks and more vibrant colors that sit boldly on the page.
• Quick-Drying & Bleed-Resistant: The optimized ink formula adjusts the ratio of liquid and solids, allowing the liquid to dry quickly while keeping the color material on the paper—preventing bleed-through without sacrificing drying speed.
• Refined Design: Lightweight and functional with a comfortable grip and a stainless steel clip. The knock-type mechanism ensures easy, mess-free use.
• Limited Edition Ink Colors: Koinu (Puppy) Color, Watagashi (Cotton Candy) Color, Asagao (Morning Glory) Color, Kingyobachi (Goldfish Bowl) Color, Koneko (Kitten) Color, Hitsuji-gumo (Woolly Cloud) Color
