Chalk Marker Uni-Ball ChalkGlass 10.1.0389

Advantages

The ink is odour-, solvent- and alcohol-free, providing a write-on/wipe-off finish that can be removed with a damp cloth while remaining water-resistant in rain. Available in bullet or chisel tip options, the marker creates consistent, vibrant marks on glass and other non-porous surfaces.

Suitable for

• Shop and café window signage

How to use

Shake the marker before use and press the tip down several times on scrap paper until the ink flows. Write on clean, non-porous surfaces such as glass, plastic or glazed boards. To remove markings, wipe with a damp cloth; for heavier residue, use a mild cleaner compatible with the surface.

Usage recommendations

Store horizontally when not in use to maintain even ink flow. Test on a small area before applying to specialty surfaces. Keep cap closed to prevent drying.
