Insert the enclosed sticks into the fragrance bottle so they can absorb the oil. Allow the fragrance sticks to fill your room naturally. The fragrance sticks enable the oil to continually evaporate, creating a subtle and luxuriant fragrance. The fragrance sticks give a wonderful subtle fragrance without the need for turning them around. However, if you'd prefer a more intense perfume experience, the sticks can be turned around to suit your preference. Please wash your hands afterwards with water and soap. Note: if you turn the sticks a lot it is possible that they last shorter than 5 months.
