Chalk Glass Marker Rystor yellow – liquid chalk marker for glass and non-porous surfaces

Rystor yellow chalk glass marker is a liquid chalk marker formulated for clear, opaque marking on glass, windows, mirrors and other non-porous surfaces. The bright yellow ink lays down smoothly for visible signage and decorative work and is removable from smooth surfaces with a damp cloth without leaving permanent residue when used as directed.

Advantages

The marker offers high-opacity yellow pigment that remains vivid on transparent and dark backgrounds. Its liquid-chalk formulation provides consistent ink flow and a smooth finish without scratching the writing surface. The tip size and ink viscosity enable both bold lines and finer strokes depending on angle and pressure. The ink cleans off glass and other non-porous surfaces with water or a mild cleaning solution, making it suitable for temporary messages and displays.

Suitable for

• Window signage and promotional displays in shops and cafes
• Restaurant and café menus on glass or mirror boards
• Event decoration and temporary art on windows and mirrors
• Labeling non-porous containers and smooth surfaces for short-term use

Key specifications

• Ink type: liquid chalk (water-based)
• Color: yellow (opaque)
• Suitable surfaces: glass, mirrors, windows, glazed tiles, whiteboards and other non-porous surfaces
• Removability: removable from smooth surfaces with a damp cloth or mild cleaner
• Finish: matte/opaque when dry

How to use

Before first use, shake the marker well with the cap on to mix the pigment and ink. Press the tip gently several times on a scrap of paper or a hidden area of the surface to prime the ink until it flows evenly. Write or draw on clean, dry, non-porous surfaces. For best results, allow the ink to dry for a short time; drying time varies with layer thickness. To remove, wipe with a damp cloth or sponge; for stubborn marks use a mild cleaning solution and rinse.

Usage recommendations

Store the marker horizontally or tip-down to maintain consistent ink flow. Test removal on an inconspicuous area before extended use on delicate or specialty coated surfaces. Avoid use on porous materials such as paper, unglazed wood or matte painted surfaces, where ink may soak in and become difficult to remove.
