This is a set of genuine Brother printer cartridges, LC111-4PK. It was found during a warehouse cleanup and includes two black cartridges (LC111BK) and one each of the color cartridges LC111C, LC111M, and LC111Y, for a total of 5 cartridges. All are unopened, but they are being sold as-is because they don't have boxes. The recommended use-by date is unknown, but Brother's vacuum-sealed packaging seems to be better than EPSON or CANON's, as I haven't seen ink bleeding inside the pouches. I have a better impression of them than other companies. However, please understand that I cannot guarantee that there will be no problems.
