Creativ Company Chalk marker

Non-permanent, water-based washable chalk marker that produces a chalk-like writing and drawing result. The marker can be used on all smooth, non-absorbent surfaces such as windows, glass, porcelain, plastic, mirrors, etc. - simply wipe off with a damp cloth. Shake the marker vigorously for about 20 seconds before use to distribute the color pigments, and then press the tip up and down on paper several times to pump the color into the tip. The liquid chalk in the marker is semi-opaque and can be applied to many surfaces as long as they are smooth and non-absorbent. The chalk is water-soluble and easy to remove. Please note that the colors may fade over time.
