This is a very useful battery storage box, which can to some extent prevent moisture
It can be used for storage of AAA model batteries, AA model batteries, and button cells（CR2450、CR2025、CR2032）
The button cells compartment can be separated from the main body, and the button cells will not fall out after being placed in the case, no matter which position you place it （you need to put the button cells into the slots with a little bit of strength，just like the bullets reloading）
The overall color scheme can be processed according to one's own needs

Provide two types of cover with the fonts of chinese and english, So you can choose the one you like
