a simple lengthwise LR44 battery case. fits 16 batteries
the top slice smoothly except for one little notch on the left that act as a retainer. can be filed down a bit to fit your preferred friction level
I didn't like any of the other cases, they're usually too big, dont fit the right number, or have bad closure systems: usually with a vertical box top, but then they dont expose the batteries: requiring you to flip the whole box over to get to the batteries
this one has a sliding top so you can expose just the 1 or 3 batteries that you need and flip those out
