Hole Punch Money Pocket
The best way to hide something is hiding it in front of everyone's eyes! It is very unexpected and if someone was in search of something that you hid, they would probably get lost in detail by searching drawers or other parts of your room again and again. But they wouldn't have a clue where you hid your money. A hole punch is a great item to use this way especially if you are a student. That's because it barely ever gets used! It probably sits somewhere in your drawers and gets used very rarely in case you are not in an office. Even if someone takes it to use, they probably won't open it to empty the paper pieces. You can even put gold coins in it if you want!
Supplies
A hole punch is all you need.
It is very self explanatory as it seems. Just open it up, empty the paper pieces and it's ready to use.. It doesn't damage the money in it but test it with paper inside just in case. It may be different in various paper punches.
