The Diptyque 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. With a scent diffusion process that uses no heat, relying on gravity and osmotic action, the hourglass diffuser preserves the originality and integrity of the brand's Baies perfume as it slowly, subtly, and delicately releases its inimitable notes into the air. The refill hourglass diffuser Baies allows you to extend the unique experience of this atypical diffuser.Diptyque hourglass diffuser refill75ml
