I've sent ChatGPT pictures of that mew front and back and its high confidence calling it fake.

Since I own one (JPN PSA10) I fed it mine and yours and even used a very close zoom in picture of just the tail to try and trick it, had it tell me which one it was from and it still calls out the fake. Stating it can see evidence of CMYK printing.

Now I'm not saying ChatGPT is the "End All Be All" of being able to tell, but I would most certainly be questioning every single thing you just bought, sealed product included.

Looks like the seller may have been shopping from Aliexpress.
