Perfume for the environment. Small rattan or bamboo sticks have been perfected to absorb and spread perfumes. The intensity of the perfume can be changed by immersing more or less sticks in the perfume and also rotating them whenever the diffusion becomes less effective. Avoid exposing directly to heat sources and air conditioners, which can alter the fragrance and accelerate the evaporation period. Fragrance: 1920s the beginning. Many things began in the 20s of the last century. The skirts have shortened, the women emancipated, the joy, the freshness and the joy of living have hunted the old ghosts. New unpublished and surprising notes have created an olfactory fury that gave rise to the modern art of perfumery.
