I have had one of these change purses for many years, and it is so useful that I thought I would get a backup.  Years ago they were a give away promotional item with logos on them.  Now they are hard to find.  It really comes in handy when you are traveling to seperate foreign currency from your pocket change.  It is also very handy when going through security screening at the airport.  No more digging for change and gathering it up at the end.  I have also used it for transporting SD cards,
 and storing turkey mouth calls when hunting turkeys.  A simple, useful design that you can find many uses for.  I have read reviews of similar items, but these are the "real item" as I remember from my youth.  Not a thin, cheap immitation.  I don't need 5 of them, but they will be nice stocking stuffers for my grown sons and spouses.
