P.18 is a creation from the Sketchbook collection by Xerjoff, launched in 2025 in a limited edition of 150 bottles worldwide, available exclusively through the official website and the house's boutiques. Drawn from the notebooks of Sergio Momo, the collection names each perfume after the page on which it was sketched. P.18 is a study of the manifestations of desire, built around a dominant pairing of tobacco and vanilla, preceded by a floral and spicy introduction.
