Marker pen Donau D-oil round 2.8 mm tip, green — oil-based marker

Donau D-oil round 2.8 mm tip, green is an oil-based marker designed for writing, labeling and marking on paper, cardboard and other porous surfaces. The round 2.8 mm nib produces medium-width lines that are suitable for everyday office, school and warehouse tasks. The ink formulation provides steady flow and visible green color for clear identification and short-term marking needs.

Advantages

The oil-based ink resists smudging on porous materials and maintains consistent coverage across the tip. The round 2.8 mm nib balances precision and speed, enabling both legible text and quick marking. The marker’s design supports extended, uninterrupted use thanks to a uniform ink feed and a cap that helps preserve the tip and reduce drying when stored between uses.

Suitable for (tasks / use cases)

• Writing and labeling on paper and cardboard
• Marking inventory, files and folders in office or warehouse environments
• Schoolwork and classroom use for visible, medium-width lines
• Temporary markings on porous packaging and shipping materials

Key specifications

• Ink type: oil-based
• Tip shape: round
• Tip size: 2.8 mm (medium line)
• Color: green
• Suitable surfaces: paper, cardboard and other porous materials

How to use

Remove the cap and test the marker on a scrap of the intended surface to confirm line width and color. Apply even pressure to create continuous medium-width lines; a lighter touch will produce thinner strokes while more pressure yields slightly broader marks. After use, replace the cap securely to prevent the tip from drying. Store the marker horizontally or with the cap on in a cool, dry place.

Usage recommendations

For best results, use Donau D-oil on clean, dry porous surfaces. Avoid use on non-porous materials such as plastic or glass where adhesion and drying may be inadequate. If long-term durability of the mark is required, test compatibility with the surface and consider a complementary product designed for permanent marking on non-porous substrates.
