Plastic cases for safely storing floppy disks. It seems they can also be used for MO disk cases. Set of 4. Not sold individually. These are cases for floppy disks. Floppy disks are not included. Although they are new and unused, they are listed as "like new" due to long-term storage. Although I have inspected them myself, there are no cracks or stains on the cases. Due to shipping costs, I will remove them from the packaging for packing. Please purchase only if you understand that they have been stored at home for a long time.
