Your toothbrush is a simple little item. Basically a stick and few bristles. Not something we think alot about. But years of travel have shown us that an inexpensive toothbrush case is key. Toothbrush cases keep your wet brush away from your other items and vise versa. And they ensure that you're not brushing your pearly whites with the accumulated dirt of your trip or the latest hostel bathroom. The only thing to consider when buying a toothbrush case is that it is vented to prevent mildew. So buy a case, stay healthy and keep those chompers clean!
