Solar cardboard night lights, awarded in 2014 at the Maison et Objet exhibition, have been manufactured in France since their creation. Each consists of a pre-cut cardboard board, an exclusive solar module (and adhesive) and come in a pouch that is easy to send by post. These objects that illustrate the values of sustainable development (local, inclusive, inclusive, solar, solar, recycled, recyclable, zero plastic, and cheap) are infinitely customizable. They are in the form of small houses or buildings or even lanterns. Sometimes souvenirs, sometimes educational kits, or simply night lights, they can be assembled without glue or scissors.
