Yes hush77hush ....
There's definately fakes around ....
The ones I've seen are printed on a slightly 'thicker' card and are not as 'glossy' in appearance.
They also had quite a lot of 'loose shavings' hanging off the card where they'd been cut to shape.
If Goth can get her hands on any cards that have been purchased through a reputable retail outlet, then she'll have a 'reference' to go by, and the differences will hopefully be apparent.
There may of course be fakes from other sources - All I know is that my stock (the Genuine ones), were bought from a reputable outlet.
The fakes I encountered - (and which were promptly returned), were from a cheap disposal store.
They were really hard to spot at first because the cardboard presentation box had one 'genuine' card showing through the 'display window', but all the non genuine cards were behind. (So you didn't realize until you got home and opened the box).
