A Pen
A pen is always a great tool to have on hand according to Orwell. “When you are at home or in the office you never think twice about a pen, because there’s always one available,” he wrote for Travel & Leisure. “That’s not necessarily the case when you’re on the road. So throw a couple of inexpensive Bic ballpoints in your baggage, as I do, if only for filling out your customs and arrival forms without bothering your fellow passengers.”
