Japan and its beautiful, clean interior design with geometric shapes remains a great source of inspiration. Which is exactly why we named this paper mache wall decoration Maru, the Japanese word for circle. paper mache, a blend of recycled paper pulp, natural gum and chalk powder, is the planet friendly material used to create a beautiful play of spheres. Embossed to create a 3D effect and given a soft and warm spray green finish, this wall deco combines intuitive design with quiet elegance. It simply lights up the room.
