These are the original cartridges packaged with DCPJ4110DW Brother printer. The black cartridge was replaced and I have not found in the trade. Having no desire to fifty stores I looked on Amazon and found this rather interesting multipack price. This pack contains 8 black cartridges, 4 yellow, 4 red and 4 blue. My main concern was that it be cons-ways or unacknowledged by my generic printer but it's not. So it's perfect.
