Twelve small lined notebooks, each 3.54 by 5.51 inches - A6, which is the size that genuinely fits a coat pocket, a glovebox or the front sleeve of a bag.
30 sheets, 60 lined pages, on paper thick enough that a pen does not bleed through to the other side
Sewn binding rather than wire stitching, so pages stay put after months of opening
Six cover colours across the twelve, handy for splitting subjects, projects or trips
Twelve is a supply rather than a purchase: keep one per project, hand them round a class, or leave one in every bag you own and stop copying notes between them.
