Glass board markers NAGA Glastavle marker mix 4.5 mm — 4 colors (black, red, green, blue)

Set of NAGA Glastavle glass board markers with 4.5 mm rounded tips in four colors: black, red, green and blue. These markers are formulated for use on glass and other non-porous surfaces, delivering consistent, easily readable 4.5 mm strokes that are readily erasable. The pack provides a compact, color-coded solution for writing, drawing and annotating transparent or glossy boards in office, classroom, retail and home environments.

Advantages

The markers produce uniform 4.5 mm lines that improve legibility from a distance and support neat diagrams and annotations. The low-odour ink is designed to dry quickly on glass to reduce smudging while remaining removable with a standard dry or damp cloth. The set includes four primary colours to facilitate colour-coding and contrast on clear or dark backgrounds. Durable barrel construction and a visible tip width make them practical for frequent use.

Suitable for

• Writing and sketching on glass whiteboards and frameless glass boards
• Annotating shop windows and display cases
• Temporary signage and schedules on non-porous surfaces
• Classroom demonstrations and office presentations

How to use

Ensure the glass or other non-porous surface is clean and dry before writing. Remove the cap and apply gentle, even pressure to produce 4.5 mm strokes. Allow the ink to dry briefly to minimise smearing. To erase, wipe the markings with a dry microfiber cloth for fresh marks or use a damp cloth for more persistent residues. Replace caps after use to prevent tip drying.

Usage recommendations

For best results, store markers horizontally and avoid exposing them to extreme temperatures. Test on a small, inconspicuous area before extended use on specialty coatings or tinted glass. Use a soft cloth or non-abrasive cleaner to remove any remaining traces without damaging the surface.
