I am highly satisfied with the Tafelfolie. I have it mounted on a wooden panel and hung on the wall to my wallpaper damaging nciht. With Black angemaltem timber that looks very classy.
I use for writing chalk marker and keep neodymium magnets. Both work quite excellent with the strong magnet I can even attach stack of 8 sheets. For the normal refrigerator magnets It's maybe a little inappropriate.
