Such great same day delivery!
I opened one pack to be sure the 3DS reader would recognize the cards. While the writing on the card is Japanese, the English versions of the names appear in the game.
I use the Nintendo collector series 1 book to store them. If you're familiar with it then you know there are pictures of the cards underneath the card inserts, so you'll always know the English name.
I've finished off collecting the SP cards and regular cards!
Now on to Series 2...
