To open the classic Chanel crystal parfum flacon, use the following tip provided by Parfums Chanel in 1963:
Remove cord and paper; with index finger as cushion, tap underneath sides of stopper lightly with glass object (glass on glass being the scientific method) while turning the bottle steadily between fingers, so that the stopper will be loosened evenly.
