A mezuzah (מְזוּזָה) is a parchment scroll, on which the Shema is handwritten by an expert scribe.

A mezuzah mounted on the right side of the doorpost of a Jewish home reminds us of G‑d and our heritage. It also invites G‑d's watchful care over the home. A kosher mezuzah on the doors of a home or office protects the inhabitants — whether they are inside or outside.
