In this essay, I use the domestication framework to explore the integration process in which reusable menstrual management technologies become part of the everyday life of users. Drawing on interviews, focus group discussions and observation in online and offline sites in Argentina, this study sheds light on how technologies and users co-construct each other in the context of an emerging menstrual activism. By listening to the stories of the participants of this study, I show the potential of women's agency in transforming technology. New and not foreseen uses and meanings were assigned to the reusable menstrual technologies, however, this happens while the identities of users are also transformed in the process of domestication, illustrating how the identity of being a menstruating woman and technologies are coshaping each other.
