I purchased a couple of these for my sons who are always leaving random loose dollars in their pockets. This little clip is perfect for keeping money and receipts together while you are out. It can also hold a credit card and your license too if needed. So many folks are minimalists now and want to carry less bulky items in their pockets instead of wallets. This one is great and should last many years. It doesn't have a spring action and is solely a clip by design which means it has no mechanism to wear out. It comes in different colors too, I got a purple, a black, and a green colored one.
