here in the uk cheese strings packs of 8 have a pack of 4 star wars cards inside.
the packet says collect60+ cards the pack I got has card number 120 on the back , so is it a full set to get.
the cheese string it self is in a plastic wrap with a light saber on it all eight are different and numberd
one numberd 40 so how many different I don't know ?

Wow, that's a huge sized set for that kind of promotion. Get as many of those as you can, as I bet they'll be good for trading/selling down the line, plus string cheese isn't that fattening, haha. It's usually lowfat of skim milk mozzarella they make it from.

Can you show an example of one? (the card, not the string cheese. I know what those look like).

They are the standard UK Topps The Force Awakens set base cards. There are four cards in the 8 packs of cheese strings and two cards in the 4 packs.

Oh, OK, I've seen that set. It has red borders and looks great. I wonder if they are only putting base regular base cards in those, or if they are also randomly inserting the high number mirror or rainbow foils. There are some "Limited" edition bonus cards, too, found in the various retail combinations. Maybe the string cheese people have their own limited edition card, too.
