i had these and can confirm they're legit from mecima. i remember people talking years ago about some of these being defective or having weirdly rounded corners~
Ok I did search up Mecimapro, and they are a legit concert promoter in Indonesia... Maybe the cards are just really rare then? Like maybe they're from a limited event/concert or something like that? Idk š
Not sure + didn't research, but usually photocards don't have the idol's name on them on the backside (especially in a font like that). Also the text is misaligned on the second card - or then it's just the angle maybe? Idk, but I'd say that they are fake...?
