The PreChanMirror (プリチェンミラー PuriChenMirā?) is the main transformation item in the Happiness Charge universe. The name is short for Pretty Change Mirror. The Pretty Cures use their PreCards to transform into their Cure form, their form changes, or a different outfit with special capabilities. The Cures transform through the phrase, Pretty Cure Kururin Mirror Change!.
PreChanMirrors can be used by different Cures to transform, as Iona's PreChanMirror was also her sister, Maria. After episode 21, Iona no longer uses the PreChanMirror, but the Fortune Piano to transform.
- Not all Pretty Cures use the PreChanMirror to transform; however, most do.
