It's really easy to check if your cartridges are Brother Originals.
Simply look for the Brother hologram that is featured on every Brother Original cartridge and ensure that it displays different numbers when it is rotated from side to side and up and down.
If you are in any doubt that your product is not a Brother Original, you can check its authenticity by visiting our authentication webpage and typing in the unique ID number on your cartridge, which is found above the hologram.
