I had been looking for particularly strong magnet because just drop to my glass-magnetic wall normal magnets. Only the 3 were supplied, pinning one A4 page or postcards. Then, when the supply of neodymium magnets came has changed that. The really keep Bombenfest. So realize that I did not dare to bring the magnets in the vicinity of my storage media (!) Delivered they were in 3 sachets, in each of which a 4-he was tower magnets. The first magnet to solve was not too easy. But the last two can only be solved with your fingers is really very difficult. But you can indeed similar with a knife manage) The magnets fit anyway great about the magnetic wall and can be due to the amount of almost 1cm again quite well solve them. Before use elsewhere where even weaker magnets are sufficient but I would advise against - who knows how hard can be then solve it;)
