We all know that Red represents elegance and sexiness. German designer Reinhard Dienes has successfully incorporated sexiness, elegance, and environmentalism with his one of a kind creation called the cardboard bookshelf and sideboard. It is available in various colors like yellow, black, blue, green, but red is the most eye-catching of all. Made of cardboard, this bookshelf and sideboard form online retailer Fashion4Home is definitely an eco-friendly one. Aside from being eco-friendly, the collection looks elegant enough for any modern homes of today designed with environmentalism in mind. Presumably made of recycled cardboard, this collection is hopefully easy to recycle as well when its useful time ends.
