Add a touch of magic and professional texture to your paper crafting with our Irresistible products These are not your average products; they feature a hidden, clear-embossed ""resist"" pattern that remains white (or the original colour of the board) when colour is applied. How it Works - The ""magic" is in the chemistry. The surface is treated with a specialised coating that repels liquids. When you apply water-based mediums, the colour sinks into the untreated areas while the intricate patterns and designs ""pop"" through, remaining pristine and bright."
