A pressed powder case often includes a mirror, but the size varies greatly. A full‑sized mirror inside a pressed powder case lets you see your entire face at once. This is useful when applying powder to the T‑zone or blending edges.

The mirror in a pressed powder case can be glued or friction‑fitted into the lid. High‑quality pressed powder cases use a mirror that is sealed at the edges to prevent liquid penetration. Over time, the mirror edge in a cheap pressed powder case may corrode due to moisture from the puff.

Some pressed powder cases feature a magnifying section on one corner for precise spot correction. The lid of such a pressed powder case opens a full 180 degrees, making the mirror usable on a table. When the pressed powder case is placed flat, the mirror angle can be adjusted by tilting the whole case.

For makeup artists, a pressed powder case with a large mirror reduces the need for a separate compact. The glass mirror in a pressed powder case should be made of shatter‑resistant material. Cleaning the mirror with a microfiber cloth keeps the pressed powder case ready for use. A well‑designed pressed powder case turns a simple utility item into a pleasant application tool.
