A Costco mixed nut container. Eat the nuts, scrape off the label, and you've got something more useful than a typical packing cube. You can densely pack clothes in it, or use it as a catch all container for loose items. It's clear, so you can pick the items out easily (and the bureaucrats can inspect it), and it's rigid, so things won't get banged up. When you're at your destination, you can use it as a general purpose storage container. It also fits under your airplane seat so you can use it inside your "personal item".
