Expert+ chalk marker MN-88-091/T is a black liquid chalk marker with a broad 4.5 mm tip and a 5 ml ink reservoir, supplied in a tube-style body and sold as a pack of 10. It creates bold, opaque lines on non-porous surfaces such as chalkboards, glass, windows, mirrors and signage, and is intended for temporary, easily erasable markings for menu boards, shop displays and creative projects.
Advantages
This black chalk marker delivers consistent, highly visible strokes thanks to its 4.5 mm broad tip and liquid ink formulation. The 5 ml ink capacity in each tube-style body provides a predictable working time for lettering and graphics. The valve-action tip ensures controlled ink flow and reduces skipping, while the opaque pigment offers clear contrast on dark and light non-porous surfaces. Packaging as a pack of 10 makes it practical for professionals and teams who need multiple markers for regular signage updates or classroom use.
Suitable for
- Writing and updating café or restaurant menu boards
- Creating window and glass displays for retail
- Temporary signage for events and exhibitions
- Hand-lettering and bold decorative accents on mirrors and non-porous craft surfaces

How to use
Shake the marker firmly before use to mix the pigment. If the tip is dry, press the nib gently on a scrap surface several times until ink saturates the tip and a steady flow begins. Write or draw on clean, dry non-porous surfaces; allow the ink to dry briefly to avoid smearing. To erase, wipe with a damp cloth or appropriate non-abrasive cleaner. Store markers horizontally or with the tip down for short periods to maintain consistent ink flow.
Usage recommendations
For longest life and best performance, keep caps tightly closed when not in use, avoid porous surfaces that will absorb ink, and test the marker on an inconspicuous area before application on painted or specialty glass. For fine detail work, use light pressure or a smaller tip marker; for bold signage, apply steady pressure to use the full 4.5 mm width.
