Avec le nom de l'expéditeur et du relais-colis collés directement sur la boîte de jeux on déchire l'image, afin de pouvoir faire un emballage cadeau. De plus j'ai des doutes sur le fait que le contenu est complet, car la boîte était ouverte. Nous verrons au moment de la construction. Sinon c'est vrai que la conception est originale et à l'air intéressante.
