Just stick a few centimeters of the 19mm (3⁄4″) wide patented magnetic tape to the back of your photos, posters, calendars, etc. and a matching piece on the wall, the fridge door, office cupboard, memo board, etc. The tape strips will stick to each other magnetically. And can be just as easily taken off again. Unlike conventional removable adhesive tape, you can use this tape again and again. Ideal, for example, if you need to reposition plans and maps several times.
