Thank you for viewing. This is a brother toner cartridge TN-28J. It is a genuine product. I am selling it because it became unnecessary due to a printer malfunction after purchase. There are two new, unopened cartridges, and one opened cartridge that was used to print only a few sheets before the printer broke, so it is almost new. This is a set of three. The manufacturing date for all three is June 9, 2025 (see photo 7). As a bonus, I will include one new, unopened TN-28J compatible toner cartridge. It is new and unopened, but I dropped it during the photo shoot, and the cover is cracked, causing a slight leakage of liquid (see photos 3-6). However, this orange cover is something you discard immediately when inserting the cartridge into the printer, so I don't think it will be a problem. Please understand that this is just a bonus item. The regular price on the brother official website is 9,900 yen per cartridge, so I think this is a great deal. It is also listed on other sites, so it will be first-come, first-served. We are looking forward to your purchase! Model: TN-28J Brand: brother Color: Black Genuine
