Video: This is supposedly the 'perfect sketchbook'. Why? Because it's made from the highest quality watercolor paper there is, Fabriano Artistico 100% cotton paper (a paper mill with a lot of history and a lot of famous users like Leonardo da Vinci!), but also because it's painstakingly made. Check out how they put together the prototype in the video below.
