The case fits very well (please pay close attention to the 1st page of the bill is shorter, had the appearance of first wrong way in there and then because of the bend sides not fitted). You protect the document also up some more as if it were loose in the purse. A star deduction because the shell is only partially water-repellent. It is free to bend pages, so that they can bend more easily. When the bill but in the pouring rain over to the police and this spreads it logically, then the bill will be wet on / by the vacant posts.
It's definitely better than nothing, but be this "problem" be aware. The price review at the highest level.
