Although the material is listed as "microfiber" in one place and "stainless steel" in another, they are neither and would make terrible magnets if that were even possible. These are typical nickel plated neodymium magnets at a good price. I will not use them as fridge magnets as they are listed in the description. I think they would make bad fridge magnets because it would be difficult to pick one up and pull out when there is already something loose underneath, they are strong. If you are skeptical about their strength, search "neodymium magnet". If you have small children, I recommend that you educate yourself about the potential choking hazard of this type of magnet.
