Let me have a closer look! With this Doctor's Head Mirror, you'll see what ails your patient on Halloween. The head mirror is a traditional device that was worn mainly by physicians, and even though it's rarely used in modern medical practice, it's viewed as a stereotypically costume accessory for a doctor's costume. Made from plastic, it has a mirror-like finish. This large and round mirror headpiece measures 5" in diameter and comes with an attached elastic band that would fit any head measurement. Each mirror comes in a polybag with a header card. Silver. One size fits most. 1 per package.
