For products that contains 3.5´Double Density Floppy Disks.
Every floppy disk, which will ever be made, has already been made.
Disks are formatted and copied on original hardware, to be used in original hardware only. However, disks and drives are not what they have been after 25 years.
So in the event, that a floppy disk does not work in your ATARI ST, please get in touch. I will do my best to get you a replacement as soon as possible.
There is no guarantee on the brand of the floppy disk and its colour. They are subject to availability.
