18650 Battery Flask with Magnetic Closure (4 Cells) - Black

Great way to store your 18650 batteries and keep them clean snd organized

These battery storage containers are awesome for carrying in a backpack like I do with the shape of them. My only concern would be that sometimes it’s a little hard to open without a lip of some kind and if I get juice on my hands I can’t open it until I dry off but I love it overall.

This is a great product. The only thing needed is an easier way to open it.
