Think of a set as a cardboard box. It may have nothing in it, or it may have some things in it, just like cardboard boxes do in everyday life. In fact, it might even have other cardboard boxes in it. As you might expect, Sets as Boxes uses the empty box to represent the empty set. The empty box is shown at the top of this page. Here are some other examples.
