【Genuine Brother High-Yield Ink Cartridges】 I accidentally purchased the wrong model online. Since they don't fit my printer, I'm selling them. I have two sets for sale: one set is completely unopened, and the other set has been opened, with only the black cartridge having its bag opened. I was unable to install them in my printer, so they are, of course, unused. Although unused, please be aware that the box has been opened and the black cartridge's bag has been opened. Genuine ink cartridges, capable of printing 3000 A4 monochrome pages and 1500 color pages (approximate). - Model: LC412XL-4PK - Compatible Models: MFC-J7100CDW, MFC-J7300CDW - Print Yield: 3000 monochrome pages, 1500 color pages - Expiration Date: October 2027 Thank you for looking.
