  • OUR OWNER AND FOUNDER

    "There has been many times in my life when I've had that "oh shit!" moment.

    The first time I got my period in middle school, the first time I sneezed after having a baby... just to name a couple. I created this product out of need. A need that most have at least once in their life.

    It was important to me that the need for this product didn't overshadow the impact it could have on the environment and our consumers lives.

    My hope is that this brand and community is a comfortable place for women to communicate and uplift each other." - Sarah Fasolo
