There’s an old camping trick of transforming an empty tin box used for mints into a tiny, lightweight kit for a few first-aid, survival or fishing items.
You can use that same idea with Whiskware Snacking Containers ($14, whiskware.com), and you’ll have a lot more room than what you’d get from a 1.7-ounce tin. Two of the three plastic containers have a cup’s worth of volume, while the other is a one-third cup. All three stack on top of each other and interlock.
The twist-on lids stay secure, keeping your gear (or snacks for the trail) from spilling. The reusable containers also come in different colors and styles.
