Tonatto Freyja Shanghai is a woody diffuser. Ambience perfume. Little sticks of rattan or bamboo have been perfected to absorb and diffuse the scents. The intensity of the perfume can be modified by dipping more or less sticks into the scent and also by turning them upside down whenever diffusion seems to lessen. Avoid exposing directly to sources of heat and air conditioners, which can alter the fragrance and accelerate the period of evaporation.
