These are genuine products as shown in the photos. There are four cartridges: LC12BK, LC12C, LC12M, and LC12Y. The recommended expiration date is unknown. Please check the compatible models on the Brother website, etc. Since the recommended expiration date is unknown, please use them at your own risk. These are from the new packaging where the orange stopper has been removed. The price has been lowered to the limit, so I will not accept any offers or price negotiations. Also, please read my profile. (Regarding the ink with an unknown recommended expiration date) *Please agree to the following before purchasing. A buyer who purchased ink with an unknown recommended expiration date, despite it being clearly stated in the description, left a "disappointing" rating, saying, "I thought the expiration date would be within 1-2 years, as is common sense." Since the recommended expiration date is stated as unknown, it really is unknown. Before shipping, I shake the cartridges to check if the ink is solidified, and I confirm that the ink is liquid before selling. In the past, there was only one case where a customer reported that the ink with an unknown recommended expiration date was unusable, which was when I sold Epson 50 ink. Even then, I checked the product before shipping, and it was a perfectly good product. After consulting with the buyer, we agreed to a 50/50 solution because there was a possibility of the buyer's false claim or a printer malfunction. 〈Conclusion〉 First, please read the description and profile carefully and understand them. If you cannot understand, ask questions until you do, or choose not to buy. Also, if you have any concerns, you should refrain from purchasing from an individual. Some people later cause trouble, apply for cancellation, or request a refund, but it will end with "You understood and agreed to the description before purchasing, right?" Regarding the "disappointing" rating in this case, the Mercari administration completely dismissed the buyer's claim. As a result, a negative rating remained, but I consider this a traffic accident.
