I lost my old cartridge, so I looked and found this one. It was on sale as used, but I was lucky enough to get one that still had pretty much all of the original packaging (it would have been impossible to open this and keep that much intact) and the booklet (now I have 2!). However, I do understand why they labelled it so, as it had been compromised. Worked as might be imagined, for great price.
