This case can hold up to 20 CR2032 batteries as marked on the outside of the case. Twist the battery holder into the case to securely hold it in place so no batteries escape if dropped ect. Made from very durable plastic. There could sometimes be some small imperfections in the prints, but all work as they should. 

To screw the battery holder into the case does take a while, but just adds extra security. 

*Comes in grey and black please message me if you want black, since grey will be the default color if you buy it without mentioning you want it in black*
