The UNI-BALL PWE Chalk Marker writes on and wipes off making it the perfect tool for sign writing on non-porous surfaces such as chalkboards
Rain-resistant - so your message will hold up outdoors - but the ink is water-based so if you want to remove it simply wipe away with a damp cloth, or a little mild detergent if stubborn
Perfect for pubs, cafes and restaurant signs
Odour, solvent and alcohol free
