A blue big box contains this twins. The blue bottle is 100ml perfume, and the silver bottle is a 22ml attar. Both have the same composition, a combination of Cambodian and Indian Oud with Blue Musk. It starts strong and pungent and stays vibrant for almost 12 hours. A stinky and animalic perfume with great sillage, projection and quality out of doubt. The attar is stronger than perfume. I recommend using both at the same time.
