It all began with a notebook. Distinguishing marks: a hard black cover with rounded corners and an elastic closure. On the first page an "in case of loss" notice with space to jot down a reward for the finder. Attached to the back cover an expandable pocket for loose papers and notes. Today, the story of the iconic Moleskine notebook collection has expanded to include a whole variety of sizes and colors, textures and layouts, and even flexible covers.
