Baby Soda Bottles

Tough plastic test tubes

These Soda Bottle Preforms and Caps (30 for $25)are good for storing just about anything small you don’t want crushed, spilled, or dampened: Batteries, earbud headphones, mini-first aid kit, medicine. They can also be used to carry liquids on a plane, as they hold about an ounce under TSA’s 3-ounce limit. I’m currently using one (pictured) as a throw-in-my-bag mini-EDC kit, in case I don’t have room for the regular Every Day Carry bag.

These food-grade polyethylene test tubes are dishwasher safe, strong, waterproof and, yes, I’ve used one to hide a geocache!
