Thanks for sending me some samples!
As far as i can tell they look pretty real to me, I don’t have any modern Chinese to compare it to on hand at the moment though so I will be picking some up in the future to see what their differences are!
The card stock definitely feels thin and flimsy but everything else seems fine.
If any one has some they can compare it too i could potentially measure the thickness, the weight of the Espeons is around 1.57grams
Edit: Adding link to a comparison that has already been done Fakes are getting too good - #23 by HumanForScale
