Well this Instructable is right for you! This instructable is a pen safe. It is the epiphany on the "use it again" campaign. No need to throw it out. Put money in it!
Go to next step for the Items you need.
Step 1: Items You Need
(1) Pen you do not need anymore
(1) Dollar bill, or paper money you wish to hide from your enemies.
Thata about it!
Step 2: Remove Ink From Old Pen
Step 1 Remove the ink cartridge from the pen you wish to hide the money in. Throw it away, keep it for another pen, or feed it to your fish. Your choice. (I do not reccommend the third choice.)
Step 3: Folding the Money
Step 2 Fold the money as much as you can so that it will (1) Fit in the pen width wise, and (2) fit in the pen lengtth wise.
Below is a picture of how I folded my 5 dollar bill.
Step 4: Fitting It In
Step 4 Slide the folded money into the pen as carefully as possible, making sure that you do not bend the money.
Step 5 Now you must screw the cap;top;cover, whatever you call it, on to the rest of the pen. DO NOT worry if the money slides too far back that you cannot reach it. Take the cap off and puch the clicking part of the pen all the way down until the money pops out.
Good Luck, thank you, and keep your money safe.
