These magnets are great for making fridge magnets. Some of the black will rub off of your fingers/fridge the first few times you use them (it rubs off very easily), but it appears to be just a surface finish. They sat in the fridge for several days and there is no trace of them. They're not as strong as neodymium magnets, but they're a lot cheaper and a lot stronger than all the other magnets in our fridge.
