Toma Marker Chalk Marker 4.5 mm Red TO-292 Z 21, water-based ink for non-porous surfaces

Toma Marker Chalk Marker 4.5 mm Red TO-292 Z 21 is a water-based chalk marker engineered for clear, opaque writing and drawing on non-porous surfaces. The 4.5 mm bullet tip produces consistent medium-width lines in vivid red, suitable for temporary signage, menu boards, glass, mirrors, windows and other smooth surfaces where easy wipe-off is required. The ink formulation offers good coverage and contrasts well against dark backgrounds while remaining removable with a damp cloth on most non-porous substrates.

Advantages

The water-based chalk ink delivers bright, opaque red color without harsh solvent odors, enabling comfortable indoor use. The 4.5 mm bullet tip balances precision and coverage for readable text and simple illustrations. The marker is designed for non-porous surfaces and provides easy erasability, making it practical for frequently updated displays. The ink dries relatively quickly to reduce smudging and maintains consistent flow for uninterrupted writing.

Suitable for

• Writing prices, specials and messages on chalkboards and menu boards
• Creating temporary signs and window displays on glass or mirrors
• Retail displays and point-of-sale messaging
• Classroom activities, crafts and demonstrations on non-porous surfaces

When it may not be suitable

This marker is formulated for non-porous surfaces; it will not perform reliably on porous materials such as paper, untreated wood, cardboard or fabric where ink may be absorbed and become difficult to remove. On some glossy surfaces or under very humid conditions, ink removal may require a stronger cleaner than a damp cloth. Not intended for permanent outdoor use or for surfaces regularly exposed to heavy abrasion or rain.

Key specifications

• Tip type: 4.5 mm bullet tip for medium-width lines
• Ink: water-based chalk ink, opaque red
• Designed surface: non-porous surfaces (glass, mirrors, glazed boards, laminated panels)
• Finish: opaque, matte-to-satin when dry
• Removability: washable/erasable from most non-porous surfaces with a damp cloth

How to use

Shake the marker well before use to mix the ink. Prime the tip by pressing down on a test surface until the ink flows evenly. Write or draw on clean, dry non-porous surfaces using steady pressure to ensure uniform lines. Allow the ink to dry briefly to reduce smearing. To erase, wipe with a damp cloth or non-abrasive cleaner; for stubborn residues, use a glass cleaner or alcohol-based solution and a soft cloth. Cap the marker tightly after use to prevent the tip from drying out.

What to consider before purchase

• Intended surface: designed for non-porous materials only, not suitable for paper or fabric
• Line width: 4.5 mm tip produces medium-width lines—confirm it matches your legibility needs
• Removability requirements: check that the planned surface is compatible with water-based chalk ink for easy cleaning

Usage recommendations

For best results, clean the surface before writing and test on a small inconspicuous area. Store horizontally with the cap securely closed and avoid prolonged exposure to direct sunlight or freezing temperatures to maintain ink performance.
