Comme des Garçons' 10th Parfum series Clash focuses on fostering the strength of difference, bringing together elements that were never meant to be associated. Comme des Garçon perfume art director Christian Astuguevielle researched what comes when these two opposing raw materials collide, thus creating an entirely new form.

The association of celluloid and galbanum is contradictory, originating in opposite realms of technology and nature. Perfumer Domitille Michalo-Bertier designed this perfume merging the synthetic and organic. The formula includes lemon oil, galbanum heart,jasmine,cashmeran, dry amber and musk.
