PILOT black gel chalk for writing and drawing in indoor and outdoor settings, including construction, building-material production, equipment inspections, and fire and disaster-prevention applications.
Features
Writes on glass, metal, plastic, concrete, wood, cardboard, paper, and other surfaces, including wet surfaces.
Writing resists running or disappearing when exposed to rain or other water.
Pigment ink produces dark, clear marks with good contrast.
On smooth, non-porous surfaces, marks can be wiped away with a tissue or cloth lightly moistened with water. Erasing may be difficult or marks may remain depending on the surface and how long the marks have been left.
