This is an 8-pack of Hitachi Maxell MO disks. Each disk is 3.5 inches with a capacity of 230MB. This is a bargain pack, with 11 disks per box. Therefore, there are a total of 88 disks. They are formatted for Macintosh. Due to aging, some of the packaging is torn, but all disks are unopened, so you can use them with confidence. Production has ended and sales have mostly ceased, making these valuable disks.
