On Facebook, I found a person selling a candy Chaewon photocard for around 10 USD, and is giving me another Chaewon card (see image 2 second row card 3) as a sort of buy one get one free.
The above images are the images that the seller has provided me. I would like to ask for assistance in trying to verify the authenticity of the card through these images. If you would like to ask for other details please feel free.
