Days for Girls International https://share.google/9Shnc8BV7c8Owc5Q4
Is working to end menstruation stigma with education (for men and boys as well as girls and women), end period poverty by distributing pads and liners and underwear and also teaching how to make replacements, and give girls/women back the days they lose from school/work due to their periods.
Edit: they have now also started to distribute menstrual cups, which can be used with a pad as backup, for heavier days.
