Very small magnets with very high holding force

We bought about two years ago two Glasmagnetpinwände. It was normal, round magnets with a diameter of about 4cm.
Unfortunately, this hardly hold more than 1 to 2 sheets of paper securely to the wall.
Once it is slightly thicker paper such as when menu cards or business cards, the pile slides down on the wall. Then 2 to 3 magnets are required to fix the paper in place.

With the tiny master of magnet boards, the whole works much better.
1 magnetic ranges with ease for 5-6 sheets of paper. Only the slightly thicker above mentioned cards are 2 magnets required to hold the matter.

All in all I can only recommend these magnets.

The magnets adhere attract each other so much that you have a little trouble at first, even to separate the supplied in packs of 4 3x cubes from each other.

Only the shipping took an unusually long time in spite of Prime. But for the product's fault.
