K%M Power magnets

I am very pleased with these magnets. they are extremely powerful. If I am playing in a concert they are strong enough to hold at leasr 20 sheets of music, on the stand. I can then view each piece, in turn, without too much shuffling of paper. They are easy to grip when I need to adjust their position. They are also very robust; other members of the band have bought magnets that have not lasted very long, as the magnetic buttons soon pull out, with use. They are expensive but, in my opinion, will soon pay for themselves. That is if you don't lose them by leaving them on the stand when you pack up.
