House of Bō's eau de parfums unfold with high concentrations of raw ingredients that can be layered and combined to create a unique personalized fragrance. From the 'Tesoro' collection, 'El Sireno' is a rejuvenating floral aquatic fragrance that combines hints of magnolia and banana with silky marine notes. It's housed in a one-of-a-kind glass vessel with a hand-sculpted cap made by local Mexican artisans from reclaimed natural blue onyx stone from Patagonia.
