Waterproof Posterman Pens are designed for external use. These are waterproof and will not be washed off by rain or little fingers! However; they are easily removed with our EaziKleen, which makes them perfect for all exterior signage. They are also suitable for use on glass and any other non-porous surface. Outline your text in black when used on glass. These markers will provide bright solid colours and can be overlaid without blurring or bleeding for a striking result. Sold in a pack of 8 pens with a choice of 6mm or 15mm nib 3 white, 3 red and 2 blue.
