Vibrant, Gelly Roll Glaze Pens give a glossy, raised effect on paper, plastic, ceramic, or metal surfaces. Write with the look of embossing without powders or heat tool. Closed surface (vellum or coated) papers work best so that ink sits on the paper rather than being absorbed. They are also glossy on other papers but with less raised effects. Water-resistant glaze acts like a resist to create the look of batik; use the clear pen to add shine or create a secret message which is revealed when chalk or watercolor is applied on top.
