from the DivaCup website:
"The menstrual cup was first developed in the 1930’s. It was made from rubber latex (an allergen for many). Millions were sold in those first years by multiple companies.
Because of management issues, the companies closed and menstrual cups were hard to find. Then over 15 years ago, Francine recognized the need for an alternative to unreliable disposable tampons and pads and found a company offering menstrual cups. She and her daughter, Carinne, singlehandedly resurrected the 75 year old menstrual cup concept by reintroducing this product to the world market when it was virtually unknown. They sold this rubber/latex version for 10 years.
In 2003, drawing on their experience and expert knowledge about the menstrual cup category, they developed a modern redesign, made from soft, top-quality silicone, to meet the needs of today’s woman. They launched their own company, Diva International. Their revolutionary concept, The DivaCup, is patent-pending and ISO certified. Today, The DivaCup is the preferred choice.
The DivaCup Team has over 38 years of combined experience in natural feminine hygiene alternatives. Their passion is to provide women an environmentally responsible, convenient and reliable alternative to tampons and pads."
