Budgeting Envelopes, Zippered Wallet, 2-Pack Reusable Spending Allowance Cash Envelope System, Nylon Organizer Bag (Small, Dark Red)

I really like these for all kinds of things. Foremost is foreign travel as it fits euros without crumpling/folding. Secondly, I like the fact that the back pocket is hidden by a flap ... so I can put the bigger bills and credit cards back there w/out anyone seeing them. Thirdly, it zips both pockets at once, so nothing escapes. Fourthly, it fits in my shirt pocket and pants pocket flat w/ just a little effort (maybe could be just a tad less long) as well as my stretchy security belt. Also, as much as I sweat, the sweat did not transpire through the material! I also really liked it when they had the 5-multi color pack, because I used each color for a different purpose on a trip. I keep my phone w/ otg adapters in 1, foreign money in another, domestic money in another etc. For what you get, I think the price is reasonable
