We can’t know how many coins in our wallet when we need to pay for beverage vending machines 、roadside payment machines or others scenarios.SO I want to get a wallet which I can know how many coins in my wallet .Because of that,I thought of sticky note.It is great that we are convenient to take coins as same as tear out sticky note.SO I let jelly combine with wallet and then Sticky up with coins.It is easy to know how many coins in our wallet.
