SHARE If You Know What This Used To Contain (Originally)

Originally this was a film container, usually a 35mm film. The film would come there and then you would put it in your camera. Then when you were done, you would put it back in the container and take it to be developed. But let's be honest, we used that container t keep all sort of things. In case case, coins, my mom would put buttons, but I know of some naughty people that would put some weird substances in there ;)... Please SHARE if you know what this was!
