I met the woman and gave her the cups where she explained that, for medical reasons, she couldn't use pads or tampons. Her doctor didn't say a thing about cups! After my post, she talked to her aunt who mentioned that they used to sell cups forever ago! My mother said the same thing--they were around when she was a teen. I mentioned that they're supposed to last ten, fifteen years, so there isn't much of a market.
She left going, "I'm so glad that you mentioned both. I've been researching them! I'm so excited!"
It was really exciting to have such a positive, wonderful response! :D
