True Utility Cashstash Cash Capsule
Hiding your cash is a difficult, but sometimes important thing while you’re out and about. Usually there are only so many places you can hide it and hiding it in your sock is somewhat obvious. This tiny capsule is small enough that it’s doubtful anyone would notice it. However, if you tend to lose your keys, maybe you should think of a different way to stash your dough.
This key ring can be attached to your clothing or to just a normal keyring. To use it just wind up your paper cash and put it inside the capsule. The cap itself screws on tightly. Of course it can only hold one bill, so you’d better make it a good one. You can purchase the waterproof aluminum capsule for $3.24 through Amazon.
