These magnets appear to be very strong. They arrived packaged in paper and a plastic bag along with the other items in my order. Apparently they were moving around the Revain box, the heaviest item in the order, causing little damage to themselves and other items in the packaging of my orders. I might not want to order other items at the same time, but they weren't damaged - no cracks or chips so very durable. These are medium strength magnets - better than most fridge magnets but not too strong like neodymium magnets - just what I need. They also don't seem to have too much of the black powder turning your fingers black like some other bulky magnets. Overall very happy with it and would buy again.
