^^Acchan also had that special pack with three boxes. The main advantages is that the binder is included and that you're it's more likely you can complete the set, or at least have some trading material.
I did some math in my previous post:
Oshima Yuko Trading Card collection coming in February 2010!
That means more costume cards
These card collections are pretty cool. Double sided pics and at least some rare ones guaranteed in each box. I do wonder if I'll ever be able to spend 45 euro on a box + 15 euro for a binder + shipping and plastic sheets
The damn binder is so expensive. it doesn't even contain plastic sheets! But if you're gonna pay that amount for some cards, you would want the binder as well
