“Dase(in)” is a collection inspired by the Naica Crystal Cave, a place with toxic gases and extreme living conditions. From this idea emerges a philosophical reflection on life and death, represented by *Dasein* (life) and *Finitude* (death). The pieces were made with gelatin-based bioplastics, molded and carefully sewn to bring them to life. This approach reflects not only material and formal experimentation, but also a symbolic connection to life’s fragility and ephemerality—raising the question: *What meaning does existence take when life seems impossible?*
