INTIMINA Ziggy Cup 2 - Extra-Thin Reusable Menstrual Disc, Menstrual Cup with Flat-fit Design, Menstrual Cups Ring, Period Products (Size A)

Have used Flex disc's (disposable) and yes they can feel them but generally don't notice. I prefer the Ziggy cup (rubber, reusable) as it is more flexible and less noticeable. https://a.co/d/09xsgK70
