Weaterproof/Waterproof Box for C Batteries

This box can hold 2 C batteries stacked inside and protect it against moisture and water/rain. It only needs an O-ring with an inner diameter of 26.5 mm and a width of 3.5 mm. The lid can easily be screwed on it as its ridges on the outside provide a nice grip. Additionally, you can see from the outside, that this box is for C-batteries as there is an engraving on it.

I also uploaded boxes for AA, AAA and D batteries. Please find them in my profile!
