You would be purchasing 1 Black Toner cartridge still sealed in their original packaging. You would be receiving FREE all 4 of the color cartridges that have been removed from their original packaging and sealed in aluminum foil. They have been in the foil for about 6 months and should be fine but they are "AS IS" and as I mentioned FREE. (You would be paying the postage on the 5 items)
I bought these for a printer that died before they were installed. I got a new printer which I thought they would fit but they did not.
Sorry brand unknown for sure but it was a standard purchase; I don't buy cheap knock off.s
