This diffuser design takes advantage of the sponge's soft cushioning and porous qualities. The sponge serves both as the packaging lining and the diffuser itself. By spraying fragrance liquid onto the diffuser's surface, it diffuses through the small holes, making the scent more delightful.

The sponge’s porous nature also creates beautiful contrasts of fullness and emptiness, much like the enchanting, elusive quality of the fragrance.
