The weakest neodymium disc magnets I have ever used. I have 1/4 sizes which are much heavier. I returned them immediately. Could it be that they were defective? I've never heard of magnets failing or weakening over time. Maybe weakness is a plus? If all you need are thin magnets with double-sided tape already attached to your fridge magnets, these might be perfect for you. At least there is no risk of pinching and damaging your fingers.
