The Pen-Touch marker writes on a wide variety of surfaces including cardstock, plastic, wood, glass, porcelain, paper and metal in an opaque, bold colour. Although the markers write on many surfaces, whether the mark is permanent or not depends on the surface & conditions (washing, scrubbing, chemicals, heat, cold, etc.) applied to the mark. Ideal for writing and decorating Invitations, Greeting Cards, Signs, CD’s, Scrapbooks, Journals and Coated paper. Pen-Touch paint markers are available in 8 colours, in 3 point sizes.
