Holds SD cards. Can't say much more. I think the case itself is a bit bigger than it should be, but I assume that's because each case is designed for a standard SD card AND a micro SD card? I deducted a star for this as I don't need to store micro SD cards, but in short they work. Manufactured from Polypropylene (PP) in case anyone is wondering what is a good choice for this type of application.
