I have confirmed that it is indeed the original.
It is in good condition and would have cost more than 10,000 yen if I had bought it at a store, but thank you for selling it to me at such a low price!
Miraculously, there were no scratches, but it arrived in a brown envelope with only one sleeve and half the card sticking out. It is disappointing because it was described as carefully packaged and shipped.
It's a very expensive card, but it was put straight into an envelope in one of the gabby sleeves!
I'm not shifting my waterproof measures, so I'm really sorry.
I really hope you don't do that.
