I just purchased 50 brand new 5.25" DD floppy disks from http://www.floppydisk.com
They arrived and they well exceeded my expectations, no mould, just new looking cookie and new glossy black sleaves with no stickers on them at all.
Just letting collectors know that you can still get new old stock floppies of various kinds.
They have cheap 5.25" in grey sleaves but I went for black, more traditional appeal.
SD cards are invaluable but they just dont have track changes and the occasional R/W head hammering sounds.
I did email the suppler a couple of times before purchase and got quick replies, I was told they are new old stock floppies.
