The product is a Maxell 3.5" High Density Floppy Disk 100-Pack, with 70 Maxell floppies and 30 generic ones. These floppies are compatible with PC and are designed for use with 3½ inch floppy drives. The high density format offers more storage capacity on each disk, making them a convenient and reliable option for storing and accessing data on older computer systems. The black color indicates that they are generic in branding, but still meet the quality standards of Maxell.
