This ingenious, hermetically-sealed capsule, oval-shaped and printed with the company's symbolic codes, contains the 34 Boulevard Saint Germain scent. Simply slide one into the little hi-tech machine, then switch it on by pressing the top, and let it diffuse the scent 3 times during a 1-hour cycle (10 minutes active, 10 minutes rest). Repeat as often as you wish. Electric Diffuser is not included.
