D.S. & Durga I Don't Know What Eau de Parfum 10 ml is a woody unisex fragrance. IDKW transforms any oil into a long-lasting perfume. It is a secret combination of materials that perfumers use to enhance the notes in a fragrance. A Bergamot accord highlights the fresh notes, Vetiver acetate gives a delicate amber, Firsantol provides a persistent sandalwood, Iso E Super adds brightness, and so on. It is like the airy structure of a building: fill the inside with an oil, a scent you like, even with your beloved perfume that has now lost its trail. I Don't Know What Eau de Parfum 10 ml is designed to give depth and enhance everything it encounters. A fragrance amplifier with transparent brightness that gives every perfume a certain, as the French say, "je ne sais quoi": irresistible.
