If you're planning a vacation or trip near the water, and don't want to bring your wallet with you to the beach, store some emergency money in an empty chapstick tube.
This discreet way to carry your cash will keep it safe and dry, and allow you to leave your wallet back in your hotel room. Plus, in case of an emergency, you'll have cash on hand for street vendors or food carts, so you don't get FOMO on all the delicious local treats. And before you take your next flight, make sure your passport isn't expired. Happy travels!
