Notebooks with geometric shapes on a cover made of cotton paper printed using the risography process. This process is known for its precise and vibrant colors. The cover offers a pleasant feel, while the rounded corners and silver-coloured grid on the inside provide structure: the "Bogen" notebook is dotted, "Pfeiler" is ruled and "Feld" is blank. Risography, developed in the 1980s by the Japanese company Riso, is a stencil printing process that works without heat and consumes significantly less energy than conventional digital printing methods. The 52-page notebooks are versatile and perfect for creative thoughts and notes. The notebooks from Mr. & Mrs. Rio are ideal for anyone who appreciates a combination of sophisticated design and high functionality.

Risography is one of the most energy-saving printing processes available. Similar to the screen printing process, master foils are produced from hemp fibers, which are then mounted on a drum and penetrated by the rice bran-based ink. Each card is unique: varying ink application and a slight offset are just as much a part of the printed image as the possible slight color abrasion.
