The perfect size notebook to take on a trip to enter trip diary notes in. The quadrille "lines"  will allow sketches as well as text. I like to draw little cartoons of things I see. The  pocket inside the back cover will hold the paper ephemera that one picks up on travels. Paper seems thick enough to handle writing on both sides of a page without bleeding through. Cover is a nice warm grey color, and the whole notebook is flexible, yet firm enough to write in without support underneath.
