White plastic medicine bottle with safety cap. Bottle contains tablets and original inner seal is intact. White, dark red, and yellow label adhered to bottle reads "Enovid". The ubiquitous bottle has a long history. For chemical storage they come in narrow necked versions for liquids and wider necked versions for solids. Many 19th and early 20th century laboratory bottles came with ground glass stoppers often with molded in labels. Dark glass is used for chemicals with light sensitivity. Today plastic bottles are used where appropriate, but glass remains the storage medium of choice because of its inertness to many chemicals. Mestranol/noretynodrel was the first combined oral contraceptive pill and was sold as Enovid in the U.S. It was the first birth control pill available for purchase in the U.S. for contraceptive purposes when it was introduced in June 1960.
