A
German website,
Pundo3000.com, has conducted a study of 100 different
products by
comparing the look of the products as shown by the packaging with the actual contents inside the boxes. Quoting the website, which is in German: “All products were purchased, the packaging photographed and the contents prepared and photographed too. All products were then eaten up.” and also: “The purpose of the project is not to discredit any brands or products but to critically compare the packaging
advertising with the inside contents”.
Personally, on the chocolate Hörnchens, I think the real stuff looks better than the
photo. Otherwise, just highlights the crap that some people eat*.
