Lies Verheyen and Pieter Claessen are the founders of the graphic design agency Mazout. Together they design interactive walls that tell, captivate and enchant. They have developed a new wallpaper, better known as magnetic wallpaper, as well as magnetic stickers and magnetic chalkboard stickers, a nice alternative to the classic magnetic board. Ideal in combination with various Groovy Magnets, which can be used to hang personal drawings or notes.
