Zig : Posterman Chalkboard Pens

The marker has a large fibre tipped pen. High Opacity, Water-based pigmented ink. Marks on most surfaces, including glass, metal, wood and plastic. Great for advertisements on glass. Marks stay on glass until you wash them off with glass cleaner. Also suitable for marking paper, plastic, mirrors, wood and stone. Great on poster board and chalkboards. Instructions for use: Before use, shake the painter well with the cap closed. Press onto the tip repeatedly until the ink is visible in it (do not continue once the ink appears in the tip as this may overload it). Try using the painter on a piece of scrap paper first (not on the object to be painted until you are sure the flow is smooth). After use, close the cap well.
