What Accessories Do You Keep/Have in your Civic?

Hey Everybody,

Just wanted to kick off a thread sharing accessories that we keep in our cars. I'm trying to look for some ideas to accessorize my Civic! Share anything/everything you have in your car from a dash cam, to microfiber/cleaners to license plate frames to what you have around your rear view mirror! Anything you have on the interior/exterior that you have accessorized your Civic with, and whatever gadgets you might have.

Thanks!
