The harmoniously elaborated bird called COUCOU and its packaging were inspired by the cuckoo clock. Elegantly designed in the shape of a bird, the trinket box, which was made of stainless and Taiwan acacia, is placed inside a black cardboard box. The minimalist packaging design conveys a contemporary and superior feel, yet it also allows for a playful experience when opening the box: users are encouraged to ease it open with joy, and the black ribbon is the key. When it is pulled, the door opens little by little and COUCOU appears.
