Refill for Molecule 01 - Escentric Molecules Molecule 01 contains only Iso E Super, which, on its own, is less of an aroma than an effect. The wearer may notice a subtle velvety woody note which will vanish, then re-surface after some time, but more than this, she or he will notice the impact the fragrance has on other people, because Molecule 01 lends an indefinable radiance to the wearer. In fact, its effect is almost pheromonic. The magic of this fragrance is that it customizes and highlights your natural fragrance oils. That\'s why you often can\'t smell it yourself, but still feel complimented by others Refill means that it can be used to put in the metal box that came with your first 30 ml. However, it can also be used alone, like any other perfume. Notes: Iso E Super
