A hermetically sealed compact contains a cosmetic substance. The compact includes an integral two-piece insert having a cover piece coupled to a base piece by an integral living hinge. The cover piece of the insert has a circular cavity with a pair of ridges, while the base piece has a peripheral wall that slides within a groove to form the seal. As the integral insert obtains the closed configuration, the evacuated air makes a distinctive audible sound, indicating to the user that the hermetic seal has been established.
