I think Panini have really missed the mark with this product. It's just not a very exciting break at all.
This product would lend itself well to 90's style inserts. The "Class of 2020" would be really cool if they were an acetate die-cut around the outside of the 2020.
The "Internationals" could drop the ticket artwork with a large background image of the globe and given an all foil treatment.
Maybe make both of them something like 2 per case.
