In the 1980s, Sakura surprised the pen industry with the invention of the first gel-based ink by creating the first and original gel pen. Sakura has perfected Gelly Roll® Classic ™ White soft-flow technology to offer our most popular color in three cutting-edge sizes: 05 Fine, 08 Medium and 10 Thick. The opaque white ink stands out on dark and colored papers, allowing illustration and comic highlights. Use it to accent handwritten letters, craft in general, layered over other colors, and produce brilliant accents in your works. Use the range of thin and thick lines to create unique little details and bold marks.
