Leuchtturm1917 B5 softcover, notebooks with a flexible cover. They have 121 pages with 80 g/m² paper and numbered pages. B5 is the same dimension as for many tablets.

Details make all the difference. The pages are numbered and there is an empty table of contents for you to make it easier to organise your notes. There are several perforated pages at the back of every notebook – just in case you want to share a note with someone else. All books come with a set of self-adhesive labels which help you archive them.
