It’s a limited-edition perfume set released years ago, a travel-sized perfume set without a spray nozzle, meant to be applied directly. One perfume bottle is missing from the set, and the original packaging box is also missing. All four perfumes smell the same, but the bottle designs are different. • Four-leaf clover (lucky charm): Symbolizes good fortune. • Key to the heart: Symbolizes opening one’s heart. • Magic star: Symbolizes dazzling light. • Sweetheart: Symbolizes sweetness. (Classic version) Liquid perfume, only the bottle design is different.
