A demijohn: perfect shape inspired by nature, by a drop of water. Despite their loveliness, however, fewer and fewer of them are made today. Instead, containers are promoted which are cheaper and more streamlined both to store and to carry. Still, is it worth running the risk of losing the memory of such a humble gem? That is how La Dame Jeanne Plan has started up, with its lamps handmade with various types of wood, where the pure shape of the demijohn is being ultimately brought to light.
