This is a holder for common button/clock/coin/calculator/watch/scale/etc batteries such as the CR2016/25/32, LR44/AG13/357, and others.

I made this because I've bought a few of those value packs of batteries over the years and it's impossible to get one battery out of the package without spilling another five or six at the same time. Now I can spill all of them at the same time and then organize them in this holder.

It's made to fit a drawer in one of those little organizers, the dimensions are 155mm x 105mm x 18mm.
