34 Boulevard Saint Germain Hour Glass Diffuser refill from the Diptyque collection. The hourglass diffuser brings back the visionary world captured in perfume. As much a visual manifestation as one of smell, it is easy and intuitive to use, requiring no energy, needing no special care. It is entirely distinct from modern technologies: Simply turn the object over to begin a fragrance cycle of about twenty minutes. 34 encapsulates, with rare and precious fragrances, the scent of Diptyque's first boutique located on 34 Boulevard Saint Germain. The result is a fragrance that has an innovative and complex signature, that is neither feminine nor masculine. Size 75ml.
