We've been waiting for the travel version of Molecule 01 for a looong time, this is the refill for the gorgeous travel box. Escentric Molecules' Molecule 01 is created from the aroma-chemical Iso E Super, which works as more of an effect than a fragrance. The subtle, velvety, woody scent melds with your natural pheromones, it smell different on everyone and alluring on anyone. You will rarely smell this fragrance on yourself, Molecule 01 is more about the effect it has on others.
