The Glass Marker features a new revolutionary method of applying opaque colors to glass, plastic, posterboard, and other non-porous materials! It's a temporary paint that won't dissolve or run in the rain, yet is easily removed with a damp cloth.
All colors can be overlaid and remain bright in the sunlight. Markers make one inch-wide strokes. Each marker weighs 1.5 oz (41 g).
