Uni mitsubishi pencil ChalkGlass 10.1.0389 is a white chalk marker designed for use on non-porous surfaces such as glass, mirrors, windows, plastic and traditional chalkboards. The pen features a chisel tip that produces variable line widths, with a minimum stroke of 1.8 mm, enabling both fine lettering and broader strokes for highlighting or decorative accents. The water-based, solvent- and alcohol-free ink provides a write-on/wipe-off finish suitable for temporary signage and menu boards while resisting light rain when used on exterior surfaces.
Advantages
The chisel tip delivers consistent, controllable strokes from fine to broad, making it suitable for lettering, borders and decorative applications. The ink is odour-free and formulated to be removable with a damp cloth on non-porous surfaces, yet offers enough resistance to light moisture for short-term outdoor use. Supplied as a single white marker, it is convenient for spot replacements and small projects.
Suitable for
- Writing and drawing on glass and mirrors
- Menu and sign writing on chalkboards and café windows
- Temporary displays on plastic and laminated surfaces
- Highlighting and decorative lettering for retail and hospitality environments

How to use
Shake the marker well with the cap on before use to mix the ink. Depress the tip repeatedly if required to start the ink flow, then write or draw on a clean, dry non-porous surface using varying angles to achieve fine or broad strokes. Allow the ink to dry briefly before touching the surface. To remove, wipe with a damp cloth; for more persistent marks, use a mild detergent solution and a soft cloth.
Usage recommendations
For best results, test the marker on a small inconspicuous area first to confirm removability and appearance. Store horizontally with the cap securely closed to maintain consistent ink flow. Avoid using on untreated porous materials such as paper or wood, where ink may soak in and be difficult to remove.
