Opaque liquid based on water that can be used on windows, glass, mirrors, chalkboards, and all non-porous surfaces. It is easily wipeable when wet and not refillable. Suitable for fine writing or elegant drawing with chalk. The fine round tip delivers liquid chalk with high opacity, allowing for reliable writing and marking even on smaller areas. This edding is not only ideal for creative projects at home but is also a popular tool for businesses such as restaurants, bars, or the glass industry.
