Cambridge Imprint Hardback Notebooks are inspired by the slim patterned German Insel-Bücherei books of the inter-war period. (In the United Kingdom, King Penguins had a similar design, and later on Ladybird books shared the same format.) They have 80 pages of plain cream paper, sewn properly and bound into a slim, light hardback notebook, covered in our patterned paper, that opens completely flat.

Each notebook measures 18.5 cm tall by 12 cm wide. The front cover has a rectangular cream label.
