1/5LEUCHTTURM1917 - Notebook Hardcover Medium A5
The Leuchtturm1917 A5 is the developer's notebook of choice for WWDC26 marathon sessions, with 251 numbered pages, a pre-printed table of contents, and 80 GSM acid-free paper that handles fineliners without feathering. The hardcover lays flat after a brief break-in, making it easy to scribble between glances at the keynote livestream. Two ribbon bookmarks let you flag your daily index and the session you're currently outlining. The dotted layout is the sweet spot between freeform sketching of architecture diagrams and structured note hierarchies.
