One of each style underpants for menstruators that don't wear panties!
Wear them both or share with your MFF (mentruator friend forevs) to show some period pride and to give some representation to non-femme, masculine-of-center, trans*, non binary, and men who shed their uterine lining once a red moon.

20% of each pin purchase is donated to an organization dedicated to trans*, queer, non binary, and gender non-conforming health and well-being or menstrual health.
