"GRAVITY" is an original concept stationery set, which includes notebook, bookmark, ruler, postcard, and pen. We used red and blue color as the main colour tone which representing space technology. All images are processed in the form of pixel effect to give the impression of old computer technology. The inner page of the notebook contains little knowledge about the evolution of the universe, space and human beings. With the illustrations, we hope to provide users with interesting contents other than traditional notebooks.
