I don’t have to fold my money up to fit in it. I can fit a pen and I keep a bank receipt and a piece of paper with the date and how much money I have in it because I want to be able to save for a vehicle…. but I mean it’s a good little bag and it seems like it’s gonna hold a lot of money or items depending on what you put in it… anyways it’s a good little cheap bag and it seems like it will last a while as long as I take care of it.. which I plan to… Just a reminder, you don’t have to fold your bills in half you can keep them straight and it will hold a lot even if you put 20s in there, if I had to guess how much money it would hold I would say if you do $100 bills you’re probably looking at 20/30 of them, but if you’re putting smaller bills in there, it would be the same amount but it wouldn’t add up to the amount a savings lol if you know what I mean, sorry I had to make a joke But if you don’t mind getting a little luggage lock or if you have one at home and you’re hesitant about buying this, just buy it.. and it fits perfect in my backpack purse
