COIL BOUND NOTEBOOKS perfect for education, university and project use. The best thing about a coil bound notebook is the durability of the binding. You can open the book flat or fold it right over on its self which makes it so easy to use. The coils are flexible which means they can take a lot of abuse when putting them in and out of your bag. With a laminated cover these books are our favourites and there are so many designs to choose from.
