Permanent Marker Staedtler Lumocolor Duo Fine/Bullet Tip Blue

Staedtler Lumocolor Duo Permanent Marker Blue is a handy dual-tip marker with a fine tip for precise writing and a bullet tip for marking on almost all surfaces. The quick-drying, low-odour ink is waterproof and colour-intensive; the blue variant is designed for durable results. The marker has a locked tip, PP barrel and cap for long service life, and is refillable. It is airplane-safe with automatic pressure equalisation and complies with DRY SAFE properties so it can be left uncapped for days without drying (ISO 554).

Advantages

The dual-tip design offers both precision and bold marking in one instrument. Fast-drying, smudge-proof and waterproof ink reduces smearing and is suitable for left-handed users. The black ink version is lightfast and weatherproof; the product is xylene- and toluene-free, refillable and built with a durable polypropylene barrel and cap. The locked tip prevents accidental damage and the marker is safe for use on aircraft due to pressure equalisation.

Suitable for

• Writing and labelling on paper, cardboard and film
• Marking on plastic, metal and glass
• Office, workshop and industrial marking tasks

How to use

Select the fine tip for precise lines and the bullet tip for broader strokes. Shake gently before use if required, then press the tip briefly on a scrap surface to start the ink flow. Allow ink to dry for a few seconds to avoid smudging. Replace the cap after use to maintain performance and store horizontally or upright when refilling.

Usage recommendations

For best results, test the marker on a small area of the target surface first. When refilling, use compatible Staedtler ink to preserve performance. Avoid prolonged exposure to direct sunlight to maintain colour intensity.
