SPIRAX 581 Project Book 252 x 360mm – 20 Leaf / 40 Page, Ruled & Blank, Side-Bound

You've got a project due Friday and half your pages are stuck in a flimsy notebook that won't stay open. This SPIRAX 581 gives you 40 pages of proper paper — 8 mm ruled on one side, blank on the other — so you can sketch, write, or mix both without hunting for a second book. Side-bound and perforated, so you tear out exactly what you need and keep the rest flat on the desk. SPIRAX has been making paper products in Australia for over 84 years, and this is the sort of workhorse you reach for when the deadline's real. Add to cart and it's in your bag by Monday

• 20 leaves / 40 pages: 8 mm ruled on one side, fully blank on the reverse
• Side-bound construction keeps pages flat and prevents curling
• Perforated edges let you remove individual sheets cleanly
• 252 x 360 mm format suits A4 desk space and standard binders
• Made by SPIRAX, an Australian paper brand with 84+ years in the trade
