The wallet is the most important part of your everyday life. It keeps all the precious things such as money, credit cards, ID cards, and more. So, it is important to take care of it.
Some people don't know that they should not keep their old notes in their wallet, because it can damage them or make them lose value over time. So, if you have old notes that you want to save for a rainy day or for investment purposes, put them in a safe place like a bank deposit box or a safety deposit box instead of keeping them in your wallet.
