Chalmers likely established a small business or company, initially called 'Daintette', to manufacture and distribute her menstrual cup. She would then sell the product under multiple names.

Chalmers engaged in various marketing and sales strategies to promote her menstrual cup. This likely included advertising in women's magazines, attending trade shows, and direct sales efforts. She faced considerable obstacles due to cultural taboos and consumer reluctance to adopt a new type of menstrual product.

Chalmers rebranded or expanded her product line with the introduction of 'Tassette,' possibly as a way to modernize the image of her menstrual cup or appeal to a broader consumer base. She marketed it as hygienic and efficient option.

Due to business and marketing challenges, Leona Chalmers sold Tassette Inc. to Beverly Kenner. This marked a significant transition in the history of the menstrual cup, as control of the product passed to a new owner. However, the product would struggle to gain widespread popularity and ceased production.
