Your project has diagrams, data tables, and a layout that a standard A4 notebook just can't handle. The Spirax 581 Project Book opens to 252 × 360 mm — wider than A4, so your spreadsheets and sketches actually fit on the page. Twenty leaves, forty pages per book, ten to a pack. Enough for a semester of assignments without running out mid-report. Grab a pack, get back to work
