Pennarello gessetto Sigel GL177 nero

The Sigel GL177 Chalk Marker in black features a round 1–2 mm tip designed for fine, delicate lettering on non-porous, smooth surfaces. The water-based liquid chalk provides strong coverage on light and transparent backgrounds and can be wiped off with a damp cloth or erased dry from suitable surfaces. The pack contains two markers with a consistent 2 mm stroke width, suitable for glass, mirrors, magnetic glass boards and shop windows.

Advantages

The round tip enables precise lines and controlled lettering with a 1–2 mm line width. The water-based formula delivers excellent opacity on light and transparent surfaces while remaining removable; markings can be wiped clean with a damp cloth or removed with a board eraser. The markers are intended for use on glass and other smooth, glass-like surfaces and come in a twin pack for convenience.

How to use

Shake the marker well before use. Press the tip gently to start the flow of ink and test on a spare piece of glass or paper until the ink runs evenly. Write or draw on clean, dry, non-porous surfaces; for best results, remove dust and grease beforehand. To erase, wipe with a damp cloth or use a suitable board eraser. Store horizontally when not in use to maintain tip saturation.

Recommendations

The markers are formulated for non-porous, glass-like surfaces; avoid use on porous materials such as paper, untreated wood, or fabric. For easy removal, clean markings promptly—older or heat-exposed markings may require a stronger cleaner. Use the Sigel Delta microfiber cloth or a dedicated board eraser for best cleaning results.
