I bought a 10-pack of disks, feeling that the included storage box would be a nice bonus to keep the disks organized and protected. Unfortunately the storage box was shipped in a padded envelope with no real protection against pressure or impact during shipping. As a result the first one arrived badly cracked, and I returned it.
The replacement fared a little better, with relatively minor cracking, shipped again with no protection other than a padded envelope.
The good news is that the disks, so far, have all performed quite well. Some old disks that i have bought in the past I might expect to find 10%-20% of them would fail to format. But in this case, of the 10 disks I bought, all 10 worked. I would recommend against buying the 10-pack to get the disk box, but for the disks themselves I think this has worked out well.

These are getting hard to find! The HD ones are more plentiful but I can't use those on these vintage computers. Every one of them formatted with no issues. 400k and 800k.
Get "˜em while you can!

I was searching some diskettes for my old Amiga (it needs DSDD floppies) and I found this excellent product. I formatted the floppies without any error or bad track, and I am using them with great satisfaction. I think is very difficult in 2022 find this kind of product, very good product

It shouldn't be often that you would need this older format of floppy disk. In my case I was trying to bring an old Macintosh computer back from the grave, and this is the only format of disk it can recognize. These allowed me to make a new set of startup disks and I did get the old computer working again. Yay!

Remember - you can't just slap in a disk in a 720K disk in Windows 10/11 and have it format it - it's expecting a 1.44MB disk. You'll need to do it via command line.
