very strong adhesion

But I would like to mention 2 things that I have not considered when purchasing and with whom I have to live now:

1. The magnets are really very small, see the image with the comparison with the 1 euro coin.
2. The liability is so strong that I could hardly abbekomme the magnets away from the wall.

I wanted strong magnets, powerful magnets I've found now only I need a pair of pliers to the abzubekommen of the magnetic wall :-)

Conclusion: One should think in advance what you need magnets. If you want to now and again make the magnets often tuned, you should choose rather larger / more manageable. When the magnet 1 time something would moor and then not often used, they are exactly right.
