As has been mentioned already, wands are real. As with the athame (ritual knife), the wand is used to direct energies during ritual work. In Wicca they are one of the important tools that most of us have, and in some Traditions are requred to have.
My personal wand is made from elder and 500-year-old bog oak. Elder is the tree of the Lady, and in particular of the Crone aspect of the Goddess; while oak represents the Horned God. So my personal wand represents the energies of both of the Deities that I honor.
One doesn't absolutely need to have a wand unless you feel a desire for one. You can simply use your finger in place of a wand if you choose. Nor does a wand need to be fancy. A twig you find on the ground can become a wand if you like. But wands are not fluff, they are actual working tools in various magical systems.
