Permanent marker Pentel Green Label NN50-D — green ink, fine tip

Pentel Green Label NN50-D permanent marker in green provides a reliable solution for writing and marking on a variety of surfaces. Designed with a fine tip that produces precise lines of approximately 1.0 mm, this marker uses quick-drying pigment ink formulated to resist smudging and fading. The low-odour, xylene- and toluene-free composition reduces unpleasant solvents while maintaining durability on paper, cardboard, plastic and coated surfaces. The ventilated safety cap and a barrel made from over 80% recycled material reflect practical and mindful design choices for everyday use in office, school, labeling and craft environments.

Advantages

The Pentel Green Label NN50-D combines a fine 1.0 mm tip with permanent pigment ink that dries quickly and offers smudge- and fade-resistance. Its low-odour, xylene- and toluene-free formula is suitable for indoor use where reduced solvent smell is preferred. The ventilated safety cap enhances user safety, and the barrel constructed from primarily recycled material supports more sustainable consumption. The marker writes consistently on common surfaces including paper, cardboard, plastic and coated materials.

How to use

Remove the ventilated safety cap and press the fine tip gently onto the surface to start the ink flow. Hold the marker at a slight angle to maintain an even 1.0 mm line. For best results on porous surfaces, allow the ink to dry briefly before stacking or handling. On glossy or coated materials, test on a small area first to confirm adhesion and drying time. Replace the cap securely after use to prevent the tip from drying out.

Usage recommendations

Store horizontally when not in use to maintain consistent ink flow. Avoid prolonged exposure to direct sunlight and high heat to preserve ink performance and colour stability. For long-term labeling on items exposed to moisture or abrasion, consider additional protective coatings or a purpose-designed industrial marker.
