This set includes four large A4 hardcover spiral-bound notebooks, each with 80 pages, totaling 640 pages. Featuring a secure yet flexible twin-wire binding, this notebook lays flat at 180 degrees and includes micro-perforated pages for easy, clean tearing—making it suitable for both left- and right-handed writers. The sturdy, water-resistant hardboard cover protects the inner pages and provides a stable writing surface, even when writing while standing. The interior uses high-quality 100gsm paper that ensures a smooth writing experience and resists ink bleed-through. It features 7mm college-ruled lines and headers on both sides of the page with designated spaces for “No.” and “Date,” facilitating systematic record-keeping. The spacious 8.46 x 11.02-inch format offers ample room for classroom notes, meeting minutes, writing, and sketching; it is an ideal back-to-school essential and a thoughtful gift for family and friends.
