 Mineral pad, I've been collecting my menstrual blood for many years. It's not sort of unknown. I think that's the beauty of the product is that this medical device, if you will, is really that it's so simple. One patient that had reported that what she loved about it was that it was passive collection. I don't have to do anything. It comes whether I want it or not, frankly, right? And I think that really can open up for healthcare accessibility, not just in the US, but also on a global scale.
