Chalk Marker Uni-Ball ChalkGlass White 1 pc 1.8-2.5 mm

The Uni-Ball ChalkGlass Chalk Marker in white is designed for clear, temporary markings on glass and other non-porous surfaces. It produces a consistent opaque white line with a medium tip width of approximately 1.8–2.5 mm, suitable for writing, drawing, and highlighting on windows, mirrors, chalkboards with smooth finishes, acrylic, and glazed ceramics. The marker delivers easy-to-read strokes that wipe off with a damp cloth or glass cleaner when removal is required.

Advantages

This white chalk marker combines a smooth ink flow and reliable opacity for visible markings on dark and transparent backgrounds. The medium 1.8–2.5 mm chisel-style tip enables both slightly bold lines and moderate detail work without skipping. The ink is formulated for temporary use on non-porous surfaces and resists smudging under normal indoor conditions, yet remains removable with standard cleaning methods. The marker’s body is lightweight and balanced for controlled handwriting and sketching.

Suitable for

• Temporary signage on shop windows and display cases
• Menu boards and café glass panels

• Crafts on glazed ceramics and acrylic sheets

How to use

Shake the marker well with the cap on to mix the pigment. Press the tip down gently on a test surface until ink flows, then write or draw on the intended non-porous surface. For consistent lines, maintain a steady angle and moderate pressure; use the broad edge of the tip for wider strokes and the narrow edge for finer lines. Allow the ink to dry briefly before touching to reduce smudging.

Usage recommendations

Before marking a large area, test the marker on a small, inconspicuous section of the surface to confirm removability. For longer-lasting temporary displays, avoid exposure to direct rain or heavy abrasion; for removal, use a damp cloth or standard glass cleaner and, if needed, a non-abrasive scrubbing pad.
