Chalk Marker Expert+ MN-88-091, black ink, 4.5 mm round tip, 5 ml

Chalk Marker Expert+ MN-88-091 in black ink features a 5 ml reservoir and a 4.5 mm round tip designed for writing and drawing on non-porous surfaces. The marker produces opaque, consistent strokes that are suitable for temporary signage, menu boards, glass, mirrors and other smooth surfaces. Ink is formulated to be removable from non-porous surfaces with a damp cloth, making it appropriate for applications that require periodic updating or short-term decoration.

Advantages

The round 4.5 mm tip provides a balance between fine detail and visible line width, allowing legible handwriting and bold strokes. The 5 ml ink reservoir offers a reliable writing duration for everyday use on boards and windows. Black opaque ink ensures clear contrast on light backgrounds and good visibility from a distance. Because the ink is water-based and removable from non-porous surfaces, the marker supports temporary messages without leaving permanent marks when cleaned correctly.

Suitable for

• Chalkboards and blackboards in cafes and restaurants
• Glass and windows for promotional signs
• Mirrors and glass surfaces for temporary decoration
• Menu boards, price tags and point-of-sale displays
• Crafts and hobby projects on smooth, non-porous materials

How to use

Shake the marker well before use to mix the ink. Press the tip gently on a scrap surface or press the nib against the board until the ink flows evenly. Write or draw on clean, dry non-porous surfaces using steady strokes. Allow the ink to dry briefly to reduce smudging. To remove marks, wipe with a damp cloth; for older or more stubborn marks, apply mild cleaning solution and wipe clean. Store the marker horizontally or with the cap securely closed to maintain tip condition and ink flow.

Usage recommendations

Test the marker on a small, inconspicuous area before full application to ensure compatibility with the surface. Do not use on porous materials such as untreated wood or paper if removal is required. Replace the cap after use to prevent drying and store at room temperature away from direct sunlight.
