Abstract
We are testing marketing strategies for selling menstrual cups to women in self-help groups in rural Tamil Nadu. These cups can save women money, improve health, and facilitate school or work outside the home. We test vivid presentations, free trials, and word of mouth.

Interventions

Intervention(s)
We provide a vivid marketing presentation to women in self-help groups in rural Karnataka.

In some groups we provide free trials for 3 months. Women can pay for the cup after 3 months or return them for disposal and owe nothing. We encourage, but do not require, that women share their experience with the cups.

If multiple women in a group volunteer for a free trial, we randomize which women receive one.
