This is a storage case for floppy disks. Each compartment holds 5 disks, for a total capacity of 40 disks. The dividers move upwards, making it easy to take out and neatly store the disks. I had floppy disks, which I am selling separately, stored in this case. If you purchase this along with the floppy disks, I will offer a discount (please contact me in advance). It has been stored in generally good condition, but please assume there is some age-related deterioration.
