An innovative concept aimed at challenging the taboo surrounding menstruation. It involves creating a collection of jewelry using menstrual blood as a material, breaking stigmas associated with periods. It seeks to revalue menstrual blood as a resource for product design and manufacturing, particularly through a collection of rings. By experimenting with biologically based materials, the project merges art and science, pushing the boundaries of body materiality. The proposal's sustainability lie in its unconventional use of taboo materials and its potential to provoke meaningful social impact.
