A4 notebook with Leuchttrum1917s Whitelines system. Instead of grey lines the background is light grey with white lines. Personally I love the white line system, you will be able to write in beautiful straight lines without any disturbing lines visible afterwards. 60 sheets (100g/sqm paper), all removable.
Leuchttrum1917 also developed an App both for IOS and Android with digitalise your notes and sketches. They call it Whitelines Link and it will capture your notes automatically so you easily can share it with friends a colleagues via various platforms.
