Genius baggie over toothbrush

I have a couple trips in my future (woop!), so as I think about what I'm going to pack, I'd like to make a contribution to the collective travel and packing tips of our time.

Cheap and easy toothbrush cover

Take one of those little extra-button baggies that come with new clothes, dump out the buttons (obviously), and place it over the head of your toothbrush. Push the seals together on either side of the toothbrush handle. Relish in the ingenuity.

Genius. Brilliant. Remarkable. Life-changing. Do it.
