Review (2/5): Not industry standard 26mm
I bought these with the intent to repress several eyeshadows and move them into a magnetic palette and wanted pans that were the same size as the 26mm eyeshadow singles that I already have. The problem with these is that they take the measurement from the outer edge of the pan rather than take the inner dimension; they also use very thin metal. They end up being too different from the normal 26mm pans that most eyeshadow singles come in to blend in with them in a palette if that's what you're going for. I wouldn't be so upset about it, but these are not returnable at all and I bought two packs of 50 based on the product description.
I'm giving them two stars instead of one because they are likely fine for anyone who just wants magnetic pans and doesn't care about the size so much. A magnet will hold them but because the metal is thin they don't stay down as firmly as normal magnetic singles do.
