I know virtually nothing about the brand but the material shows significant shine and fuzziness on my screen so IMO they cannot be cotton and cannot be authentic. They’re also cheaply and sloppily stitched. Wait for others.
You can also do a burn test to identify the fiber. Gently pull some of the fuzz off an interior seam and burn it in your sink. Synthetic fiber will burn to a hard little ball but cotton will burn to ash.
