Bt21 RJ and Mang Transparent Cards. I bought these 2 from an Instagram GO manager, peachikatie and she sold these to me. They are official, but there's slight scratches on them (that's how she sent them), but they still look nice! I'm selling these 2 as a set, so pay $15 and I'll ship you both c: thanks for checking out my listing! The size is like a photocard/ ID
