very strong adhesive magnets

The magnetic adhere very strongly, several sheets of paper are held without problems on my magnetic board. Should it be something too much, then you just take 2 pieces.
The Start adhesive force makes the separation of 2 magnetic bit more difficult, because the magnet to hold are quite small then.
Visually I think the magnet also quite well, rounded corners and edges. In so far nothing is chipped.
I'm very happy with it.
