Collection: Master (A4+)
Our largest notebook format. Master (A4+) measures 8.75 × 12.5 in. — generous space for diagramming, project planning, sketching, and the kind of work that doesn't fit on a smaller page. Hardcover editions hold 235 numbered pages of 100 gsm FSC-certified paper; the Master Slim format trims the page count to 123 for a thinner, lighter book. Each one carries the LEUCHTTURM1917 details: blank table of contents, two page markers, gusseted pocket, elastic enclosure band, perforated detachable sheets, and a thread-bound binding that opens flat. Four ruling options. A serious notebook for serious paper work.
