Stabilo created the highlighter in 1971. Since then, they have improved it with 4h anti-dry-out technology, and an assortment of 9 fluorescent and 6 pastel colors. The Boss Original is also environmentally friendly, and easy to refill. Water-based ink and 2 line widths- 2mm + 5mm.

BOSS ORIGINAL highlighters feature a chisel nib that allows two different line-widths, a distinctive design that keeps them from rolling away and water-based vibrant ink that is suitable for paper, copies or faxes.
