For a while I used small boxes backed with tape to store the batteries I carry in my travel backpack. It's better than straight duct tape, which leaves horrible marks, but the boxes deteriorate over time and the batteries fall to the bottom of my bag. This little product is great. The AA option is very common and therefore very affordable. They're made in the USA, and regular brand name batteries (I have the main ones and one of my own to test) fit comfortably with little wiggle room. They seem pretty researched, but I'll check them out here soon. I'll update this if I run into any issues, but I'm a little skeptical. Plastic feels pliable, not brittle, so I'm not afraid of falls.
