I take this small SuperMagnets as a tie holder. Ok, that might sound corny, but is very handy in my job and in addition looks cool. No Matter. Anyway, I had read that other magnets suffer if they sometimes fall to the ground. This is definitely not the case here. I am also impressed with the tremendous strength that even now, after months of use, has not decreased. Those things are so strong that you can tell them apart only with difficulty draw - despite the fact that they have a diameter of only 6mm.
