In the 1980s, Sakura surprised the world with its invention of the first gel-based ink. Since then, the creamy, colorful Gelly roll has remained a favorite for the bright color selection, special effects, and smooth ink flow. Sakura has perfected this ink technology to now offer our most popular color in three nib sizes. Gellyroll classic White is now available in 05 fine, 08 medium, and 10 bold. The opaque quality of the White ink makes it ideal for writing clearly on dark and colored papers.
