Custom properties are a way to store your own meta-data in Blender’s data-blocks which can be used for rigging (where bones and objects can have custom properties driving other properties), and Python scripts, where it’s common to define new settings not available in Blender.

Only certain data supports custom properties:

To add a custom property, find the Custom Properties panel, found at the bottom of most Properties Editor, and hit Add.
