We have a magnetic wall of glass. This is not a standard commodity, but a special design. The wall is absolutely great, but a very strong magnet set is due to the glass thickness required, otherwise no (really not a leaf) can be fixed to the wall. The delivery was very quick and the packaging is also no reason for complaint. The magnets are very strong and just as they should be. Now hold several A4 pages or postcards to the whiteboard and the magnets can also be very easily removed from the glass wall. Note: However, you should be careful and not let each other magnets "popping". While this is also happened to me several times, but they are then more difficult to separate from each other. I turn then getting away from each other, which I can then relatively easy to solve. A chipping on the surface, I had not yet.
For a glass magnetic board clearly a buy recommendation!
