If you don't feel safe keeping your money stored up in a bank and don't have enough money to buy a high-end safe, the Coca-Cola Secret Stash Safe may be what you've been searching for. It looks just like any ordinary Coke bottle, so no one will ever suspect that you are hiding wads of cash inside it.
You could have the Coca-Cola Secret Stash Safe out in the open and people wouldn't have a clue that your life savings are in there. The only thing is that you'd have to be careful that no one attempts to take a sip from this interesting bottle. There's also two-liter and pop can versions available if you have more or less cash to stash.
