Kensington 3.5" & 5.25" Floppy Disk Drive Cleaner w/ Solution Kit. Shipped with USPS First Class.
The set is still sealed. I am pulling these out of a case fresh. But these are old and from 1996. That being said, The isopropyl alcohol and the little black vial has dried up. You'll have to replace the isopropyl alcohol yourself.
