These uniquely designed Fineliner are a favorite among professionals, academics, students and organizers of all kinds. Ideal for color-coding, editing or studying, the Original Fineliner features a chisel tip that allows two different line-widths and a geometric design that keeps them from rolling away. The vibrant ink is suitable for paper, copies of faxes. Don't worry if you accidentally forget to put the cap back on: thanks to STABILO Anti-Dry-Out technology, this highlighter can be left with its cap off for up to 4 hours without drying out.
