DP Pokemon Festa Card Files


Does anyone know exactly what these are and where they came from? Also, what are they worth? I think the are from DP Festa Promos but not really sure. I can’t find them anywhere. Here are two pictures:


Any help is appreciated. Thanks!

Yeah, I think the cards are the exact same as the DX’08 pack, but I know that these specific folders were given out at some event. Hopefully someone can help. Thanks again!
