This STABILO highlighter combines high-quality with sustainability, and is the perfect choice for environmentally conscious consumers. Made from 83% recycled plastic to help conserve natural resources and reduce landfill, it is easily refillable with a STABILO BOSS ORIGINAL refill. Ideal for long periods of work, its Anti-Dry-Out technology stops it from drying out for up to 4 hours if the cap is left off. Thanks to its super-versatile slanted tip, the STABILO GREEN BOSS is capable of drawing lines of varying thickness (2mm or 5mm) from wide marks for blocks of text to thin lines for annotations, underlining and ruled lines.
