The Cloud Collection Travelsize Set in an elegant gift box contains all 3 Cloud Collection fragrances in 10 ml spray bottles. The unique perfumes are the first in the world to react to the environment, weather, and the wearer's personal aura. Once the 2 phases separate, the diamond-shaped scent molecules at the bottom of the bottle begin to sparkle. The effect becomes more visible when the bottle is held against a light source. The slim glass bottles with the elegant, gold-colored metal cap fit into any handbag, making them wonderful for on-the-go use.
