If you have a bunch of 2032 coin cell batteries or need to carry a bunch of 2032 coin cell batteries, this is a really handy device that allows you to carry 20 of them in a small stack and keeps them seperate so they don't short circuit and die out. The best part is the way it feels to put the battery in, almost like a magnet where they spring into place, and ejecting them is easy and fun with a little push from the thumb to spring out. I didn't expect this to be as much fun as it is, so I figured I would share it with you in case you need to organize your battery life :)
