Donau oil-based marker DONAU D-Oil round 2.8 mm tip blue

Donau oil-based marker DONAU D-Oil round 2.8 mm tip blue is an oil-based marking pen designed for durable, high-contrast lines on a variety of surfaces. The round 2.8 mm tip produces medium-width strokes suitable for clear labeling and legible writing on paper, cardboard and many plastics. The formulation promotes consistent ink flow and reliable coverage for everyday office, school or warehouse tasks.

Advantages

The oil-based ink provides good adhesion to porous and semi-smooth surfaces and resists smudging once dry. A round 2.8 mm tip offers even, continuous lines that are easy to control for both writing and simple drawing. The marker is intended to deliver consistent performance across repeated use, maintaining color intensity and minimizing interruptions due to uneven flow.

Suitable for

• Labeling boxes, files and folders
• Marking plastic containers and packaging
• Writing on cardboard and paper for organizational purposes
• General-purpose marking in offices, schools and warehouses

Key specifications

• Ink type: oil-based pigment ink
• Tip shape and size: round tip, 2.8 mm
• Color: blue
• Line width: medium (approx. 2.8 mm stroke)
• Suitable surfaces: paper, cardboard, many plastics and similar materials

How to use

Shake the marker gently before use to mix the ink. Remove the cap and press the tip lightly on a test surface until the ink starts to flow evenly. Write or draw using steady pressure to achieve uniform lines. Replace the cap securely after use to prevent the tip from drying out. Allow the ink to dry fully on the surface to reduce the risk of smudging.

Usage recommendations

For best results, test the marker on an inconspicuous area of the material before extended use, especially on glossy or coated surfaces. Store horizontally or with the cap tightly closed at room temperature and avoid exposure to direct sunlight or extreme temperatures.
