Volatile composition dispenser with visual indicator

A volatile composition dispenser including a solid article having a volatile composition and a peripheral evaporative surface. The solid article is capable of shrinkage relative to the peripheral evaporative surface from an initial size to a reduced size smaller than the initial size upon exposure of the solid article to the environment in an interior space. The solid article is characterized by a shrinkage in a direction away from the peripheral evaporative surface of greater than 1% to less than 40%. A visual indicator is located proximal to the peripheral evaporative surface of the solid article. The dispenser has a first configuration in which the visual indicator is not visually perceptible, and a second configuration in which the visual indicator is visually perceptible upon shrinkage of at least a portion of the solid article from the initial size to the reduced size for indicating a state of use of the dispenser.
