This marker has a 1/4" wide chisel tip that makes a 6mm wide mark. High opacity, water-based pigmented ink.
Suitable for marking on most surfaces, including glass, metal, paper, mirrors, wood, stone and plastic. Great on posterboard.
Works well for advertisements on chalkboards and glass surfaces. Marks are waterproof and will stay on glass until you wash them off with glass cleaner. Marks wash off chalkboards with a standard ammonia-based household cleaning solution. This is a favorite chalk marker for many sign artists!
Safe / Non-Toxic.
