Stash your cash in a tiny capsule

Name: True Utility CashStash

What it is: A tiny capsule made of aircraft-grade aluminum and capable of holding one bill of pretty much any currency. It also has a rubber O-ring to keep water out.

How it works: Fold a bill lengthwise, screw off the cap, pull out the metal clip and clip the bill in the middle. Then roll the cash to micro-size and insert into the capsule.

The good: This is one of those simple travel goodies that are incredibly handy. For the beach, when you don’t want to rely on the old money-hidden-in-the-shoe trick, this is terrific. Just clip it to your swimsuit.

The bad: Learning to fold a bill small enough to roll around the clip may take some practice.

Cost: $5.99.
