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.
