Car Coffee Cup for Storing and Sprinkling Flour

I have a car coffee cup that has a screw on lid, and a little tab that opens up to a little hole, where I can drink coffee from. I got tired of getting flour all over everywhere when I just needed some sprinkled on my cooking projects. So I use the coffee cup with the lid to hold flour and then I can open the tab and sprinkle the flour without making a mess. It is much more efficient that way.
