Marker Donau D-oil oil-based 2.8 mm black, Donau 7369001PL-01

Donau D-oil is an oil-based black marker with a 2.8 mm rounded tip designed for writing and marking on paper and many smooth surfaces. The ink provides consistent flow and produces clear, visible lines suitable for everyday office and school tasks as well as for warehouse labeling and general-purpose marking. The marker delivers durable, fade-resistant marks that remain readable over time.

Advantages

The oil-based pigment ink resists smudging on most non-porous surfaces and offers reliable opacity on light and medium-colored substrates. The 2.8 mm tip balances precision and coverage, enabling both line work and thicker strokes. The marker’s construction supports continuous ink flow and consistent performance during extended use.

Suitable for

• Writing and annotations on paper
• Labeling boxes, containers and shelves in warehouses
• Marking smooth surfaces such as plastic, coated cardboard and laminated materials
• School and office marking tasks where medium-width lines are required

Key specifications

• Tip size: 2.8 mm rounded tip for medium-width lines
• Ink type: oil-based pigment ink for fade resistance
• Color: black
• Application surfaces: paper and many smooth, non-porous surfaces
• Line characteristics: consistent, opaque lines suitable for visible labeling

How to use

Shake the marker gently before use to ensure even ink distribution. Press the tip down briefly on a scrap piece of paper to prime the ink if needed. Write or draw with moderate pressure to achieve the intended line width; for broader strokes, vary the angle of the tip. Replace the cap after use to prevent drying.

Usage recommendations

For best results, test the marker on a hidden area of the target surface to confirm adhesion and appearance. Avoid applying the marker to highly porous or very rough surfaces where ink absorption may reduce visibility. Store horizontally or with the cap securely closed, and keep away from extreme temperatures to maintain ink quality.
