There are two versions: Korean version and mainland version. The old and new cards are all sent from the photo album, that is, a printed signature card with photos of members on the front and printed signatures on the back. The old and new cards are two versions of the card, that is, the pictures of the members on the card will be different. The Korean version has posted posters, but the MS is limited, and the mainland version has no posters. . . The mainland version is made of plastic, black is for Team M, and white is for Team K. If parents have the ability, they can buy them all, but they can do what they can. But since I have the mainland version, I'd better buy the mainland version.
